Brownian Motion

In 1827 Robert Brown, a well-known botanist, was studying sexual relations of plants, and in particular was interested in the particles contained in grains of pollen. He began with a plant (Clarckia pulchella) in which he found the pollen grains were filled with oblong granules about 5 microns long. He noticed that these granules were in constant motion, and satisfied himself that this motion was not caused by currents in the fluid or evaporation. Smaller spherical grains, which at first he took to be oblongs end-on, but later realized weren’t, had even more vigorous motion. He thought at first that he was looking at the plant equivalent of sperm—they were jiggling around because they were alive. To check this, he did the same experiment with dead plants. There was just as much jiggling. Perhaps all organic matter, everything that ever was alive, still contained some mysterious life force at this microscopic level? Sure enough, he found the movement in tiny fragments of fossilized wood! But then he went on to find it in matter that never was alive—tiny particles of window glass, and even dust from a stone that had been part of the Sphinx. The movement evidently had nothing to do with the substance ever being alive or dead, much to Brown’s surprise. So what was causing it? Perhaps it was evaporation currents, or the incident light energy, or just tiny unnoticed vibrations. But none of these explanations was very satisfactory.
Half a century later, a new possible explanation emerged. The kinetic theory of heat developed by Maxwell, Boltzmann and others was gaining credence. If all the molecules in the fluid were indeed in vigorous motion, maybe these tiny granules were being moved around by this constant battering from all sides as the fluid molecules bounced off. But there was a problem with this explanation: didn’t it violate the second law of thermodynamics? It had been well established that energy always degrades, as friction slows movement kinetic energy goes to heat energy. This seemed to be the other way round—the molecular battering was certainly disorganized heat energy, but when the granule moved it had evidently gained kinetic energy. Since many scientists regarded the second law as an absolute truth, they were very skeptical of this explanation.
In 1888, French experimentalist Léon Gouy investigated the movement in detail, finding it to be more lively in low viscosity liquids. He established that it was unaffected by intense illumination or by strong electromagnetic fields. Despite the second law, Guoy believed—correctly—the random motion was indeed generated by thermal molecular collisions.
It’s easy to see the Brownian movement, or Brownian motion (it’s called both) by looking through a microscope at tobacco smoke in air. We have a movie here.
In 1905, Einstein published a theoretical analysis of Brownian motion. He saw it as a crucial test of the kinetic theory, even of the atomic/molecular nature of matter. Previous discussions of the phenomenon had all been qualitative—Einstein demonstrated that careful observation of Brownian motion could reveal the actual size of molecules, that is, find Avogadro’s number.
If the results of such experiments were consistent with other estimates of Avogadro’s number, based on unrelated phenomena such as gas viscosity measurements and van der Waal’s equation fit to isotherms of real gases, it would be a powerful argument for the kinetic theory. On the other hand, if there was real disagreement then the kinetic theory was in serious trouble.
Einstein’s approach was based on an analogy with osmosis: recall that osmosis involves one substance (the solute) dissolved in another, the solvent. The solute has larger molecules. Now imagine a container divided in two by a semipermeable membrane, meaning the solvent molecules can pass through the tiny holes in it, but the solute molecules are too big to get through. Suppose on one side of the membrane there’s pure solvent, on the other side solvent plus solute (assumed fairly dilute), and initially the pressure on the two sides of the membrane is the same. The pressure on the side with solute is generated by both solvent and solute molecules bouncing off the membrane, so necessarily the rate at which solvent molecules are hitting the membrane on this side is less than on the other side. Some percentage of the solvent molecules hitting the membrane pass through the little holes, so what will happen is that more will pass through from the pure solvent side, and gradually pressure will build up on the solvent + solute side until equilibrium is reached, meaning equal numbers of solvent molecules going each way on average.
Einstein’s insight was that a liquid containing a large number of tiny identical particles, such as those observed in Brownian motion, was really no different from a solvent containing solute molecules. True, the Brownian particles were a lot bigger than molecules, but they were buzzing around, and would therefore bounce off the walls of a container, generating pressure. The formal analysis should be the same: the kinetic theory, with equipartition of energy, predicted they would have kinetic energy 1.5kBT. If the concentration of particles varied spatially, they would flow to even it out.
Here again he used an osmosis analogy: think of a cylindrical container, with a semipermeable membrane which is like a piston, free to move. The solute concentration is initially greater to the left of the piston.
From the previous discussion, it’s clear that the solvent will flow to the left, raising the pressure there, so the piston will move to the right. The solute molecules cannot cross the piston, so the piston will move until the solute concentrations on the two sides are equal.
The rather surprising result is that if one assumes equipartition of energy, the pressure on the piston from the solute on one side is the same as if those solute molecules were freely moving in a vacuum.
Their greatly reduced mean free path doesn’t matter: the pressure depends only on the concentration in the immediate neighborhood of the piston, and the speed of the molecules. And, this is equally true if the solute molecules are replaced by tiny but macroscopic spheres. At least, this is what Einstein asserted, and he gave a formal proof based on an evaluation of the free energy, assuming a dilute system (meaning interactions between the spherical granules could be neglected).
So we can think of the little spheres as moving freely through space (!), and although their paths will actually be very different, calculations of local pressure based on this should be correct: the pressure on the walls from the granules is therefore given by the ideal gas law, that is,
where the average kinetic energy is written W, and—if the kinetic theory is correct—this should equal 1.5kBT.
So how is this to be checked experimentally? As we shall see in a moment, the first experiment used uniformly sized tiny spheres in place of granules. The first obvious thought is that if is predicted to be 1.5kBT, perhaps one can measure the jiggling velocity of the tiny sphere a few times and take an average. This, however, misunderstands the nature of the motion: a molecule will bounce off the sphere around 1020 times per second, and although that only makes a tiny difference to the sphere’s velocity, in one hundredth of a second the average imbalance, √N, will be of order 109, enough to make a change in a small sphere’s velocity. And all the successive changes are completely random in direction, so it’s as hopeless as attempting to measure the velocity of H2S molecules in air by releasing a few and measuring the time for the smell to reach the far end of a room.
A slightly less direct method of finding is needed. Now, it is well-known that in an isothermal atmosphere of an ideal gas under gravity the density falls off exponentially with height, this is established by balancing the gravitational force on a thin horizontal slice against the pressure difference between top and bottom. It occurred to the French experimentalist Jean Perrin that this same argument should apply to a “gas” of tiny uniform spheres in a fluid: their pressure is generated by the Brownian motion. In 1908, he chose gamboge, an emulsion used for water color, which contains bright yellow spheres of various sizes. By various ingenious tricks described in his book he was able to separate out spheres all close to the same size. He was able to measure the size, he knew the density—and that of the “solvent”—so he could compute the gravitational pull. He could also measure the decrease in density with height in isothermal equilibrium.
The calculation is as follows: for a horizontal slice of thickness dh, with n spheres per unit volume, each of volume φ and density Δ, in a liquid of density δ (I’m using Perrin’s notation here), the gravitational downward force on the slice is ndh φ (Δ - δ), this is balanced by the pressure difference:
This is easily integrated to give the exponential vertical density profile.
Perrin could establish by observation and measurement every term in this equation except W, so this was a way of measuring W, assuming of course the validity of the kinetic theory.
Now equating W to 1.5kBT gives a value for Boltzmann’s constant, and hence via the known gas constant R = NAkB, a value for Avogadro’s number.
Perrin repeated the experiment with a wide variety of different substances, the experiments were very challenging, his results for Avogadro’s number were consistently between 5×1023 and 8×1023. He remarked that for the largest granules behaving like a perfect gas, a gram molecule would weigh 200,000 tons! The results were consistent with the other quite different ways of finding Avogadro’s number, and these experiments convinced even the most recalcitrant anti-atomic theory skeptics. The kinetic theory was fully established.
In 1908, Langevin gave a more direct treatment of Brownian motion. He focused on following one particle as it jiggled around. We’ll follow him in restricting the motion to one dimension—assuming the molecular collisions driving the motion are completely random, the motions in the three directions are uncorrelated, so can be treated separately and added. Finally, we’ll neglect gravity and any other external force fields.
Let’s assume, then, that we’re tracking a small spherical object, of mass m and radius a. It will experience a viscous drag force -6πaηv (Stokes’ formula). We’ll denote the random thermal molecular collision force by X, which clearly averages to zero.
Assuming the equipartition of energy applies also to the kinetic energy of our sphere,
where the average is over a long time.
The equation of motion ma = F is:
Multiplying throughout by x,
which can be written
Now we’ll average over a long time:
Since X is random, Also, The operations of averaging and taking the time derivative commute, so we can write the equation:
To solve this differential equation, write
The equation becomes:
The solution is
For the actual systems examined experimentally, the exponential term dies off in far less than a microsecond, so for a particle beginning at the origin:
so
Hence by doing multiple experiments and averaging, Boltzmann’s constant kB can be found, and from that Avogadro’s number, as before.
Note that the constancy of also appears in discussions of random molecular motion and the random path—this is all the same thing.
Exercises:
1. Estimate the decay time of the exponential term in the integrated expression for y(t) above. You’ll need to find the viscosity of water, and estimate the sphere size as a few microns.
2. Estimate how rapidly density of yellow spheres drops with height in Perrin’s “atmosphere”.
3. Notice the average distance traveled in the last equation above depends on the kinetic energy, the size, and the viscosity. This means a tiny lead sphere would diffuse the same distance, on average, as a tiny sphere of oil of the same size. But isn’t the lead moving a lot more slowly, since it has the same average kinetic energy? Explain.

Two Baby Factories Discovered In Anambra
by Seyi AdebowaleThe Anambra special anti-child trafficking task force located two houses in Obosi, Idemili North Local Government Area, and Onitsha where pregnant girls are kept until childbirth and the children sold to childless people.
The task force was led by the Anambra State Commissioner for Women and Children Affairs, Ndidi Mezue, who came across the two malnourished pregnant girls hidden in a room awaiting delivery.
The team then rescued the girls and arrested the manager of the home and promised to further investigate and act of the case.
In another inspection, a baby factory was also discovered in Onitsha.
According to an eyewitness (name withheld), only girls who had problems of unwanted pregnancies were kept in the room to keep their secret and identity till the day of delivery.
The source explained further that they are not properly fed because the home only manages to feed them to avoid much spending.
The source commented that the baby factory business had been booming because the operators deal in unwanted pregnancies by young girls outside marriage.
The source also said some poor girls are lured with money by the management of some baby homes and impregnated by men under the payroll of the baby homes.
Naija News learnt that the inspection team, which comprises operatives of the Nigerian Police Force, the Department of State Service (DSS) and the Nigerian Security and Civil Defence Corps (NSCDC), and also the ministry staff members, had visited community orphanages in Ogidi, Nkpor, Obosi and Onitsha, with the aim of inspecting the general environment, sources of water, hygiene and operational licence of facilities.

The first company we have identified is Unmanned Tech and their product is their DIY quadcopters. One of which, that being the DYS D800 X4, has a similar design and rotary placement, although ours are cylindrical rotors. The technology they are using for flight and movement are also very similar.The second company we have identified is FanWing technologies. The products they specialize in is making planes using the Magnus effect as a propulsion system. We will be using the Magnus effect in a similar way, that being achieving flight, but in the form of a quadcopter.
The Academy of Model Aeronautics is a nonprofit organization dedicated to the research and promotion of unmanned or model aviation. Companies involved include AOPA(Aircraft owners and Pilots association) and FanWing. There are over 57,000 members in the program being under 19 and approximatly 195,000 in total
Our team has designed a drone utilizing the magnus effect. While drones traditionally use rotor blades as a means of generating lift, our drone uses rotating spools to generate lift. This change could offer greater lift and stability, and the tiny benefit of less complexity in manufacturing a cylinder than a blade. In conjunction, the design still retains the core structure of a standard bladed drone, meaning that manufacturing body requires no changes to be made.
We have identified the Company HorizonHobby for being a possible manufacturer of our product. They have in the past build many quadcopters and the also sell pieces individually. This makes them a good Company candidate because they would have the materials readily available if they so need to manufacture one of our drones. This is the email we sent them, we never heard back from them:
<EMAIL_ADDRESS>Hello,
We are working on a school project in which we designed and built a quadcopter drone that utilizes the Magnus effect in order to achieve lift. We researched about the products you manufacture and see that many of your projects overlap what we are doing. Could you evaluate and see the product out team has proposed? Here’s a description of the product:
Our product is a drone that uses four motors to rotate cylinders where propellers would have normally been. The quadcopter in of itself is not that big being only 18 cm long in both length and width. It flies remotely using a dual signal input from Bluetooth and radio.
Thank you so much for your help!


Two killed, scores injured as gunmen invade bank in Ekiti
Rasaq Ibrahim, Ado-Ekiti
A security guard and a three-year-old girl have been reportedly killed after gunmen robbers stormed a branch of United Bank of Africa in Oye-Ekiti, the headquarters of Oye Local Government Area of Ekiti State, on Thursday, carting away undisclosed sums of money.
It was gathered that the eight-member armed robbery squad stormed the bank around 3:17pm with two vehicles.
The dare devil robbers who were said to have entered the town through Ayedun-Ekiti gained entry into the bank by blowing up the entrance with the aid of dynamite.
According to a source, the heavily armed robbers shot into the air to scare away residents within the vicinity of the bank in order to allow them to operate freely, as people scampered for safety.
Scores of customers and the staff of the bank were said to have been attacked with various degrees of injuries sustained.
A security guard working with the bank and a three-year old girl whose mother’s shop was beside the bank were killed by stray bullets shot by the criminals while to flee the scene
The operation lasted for some minutes before the criminals were said to have escaped through the back door of the bank.
It was also gathered that a police van which was hijacked and used to barricade the highway by the robbers was set ablaze after the operation.
When contacted, the Police Public Relations Officer in Ekiti State, Caleb Ikechukwu confirmed the incident but said the command is on the trail of the robbers.

He said: “I can confirm to you that there was a bank robbery. As I am talking to now, the operatives of SARS (the anti-robbery squad) with combined team of 33 Police Mobile Force (PMF) are trailing the armed robbers now.
“Information at our disposal is that they escaped through the bush path. We are trying to see how we can catch up with them. Preliminary investigation is ongoing as per the number of casualities”.
On whether they carted away money, he said, “I cannot confirm that”, Ikechukwu added.

At the risk of deluging you with Heppenstall, I cannot resist posting this line from The Intellectual Part:
“I had never thought highly of Esperanto (my father had once tried to make me learn it, but when I found the word for bird was ‘birdo’ I could no longer take it seriously).”
I wonder if perhaps I should arrange for Blötzmann's bird psychology diagram to be translated into a birdo psychologyo diagramo.


Kale Salad
This is by far my most favorite salad in the whole world. It's super crunchy, hearty, filling, and so ridiculously good for you. It's off the chain! You might could call it a non-dairy slaw, and one of my favorite parts is that you get to eat it with a spoon!
The ingredient list is a little vague on purpose because this salad is so flexible and it can go in so many different directions.  Wanna try some shredded beat? Go for it! How about some chopped up celery? Why not? Goj Berrs? Pistash? Cocoa Nibbies? I want all the goodies! And it's hard to say exactly how much of each thing to chop up. Just feel it out.
Ingredients
- Kale
- Cabbage
- Carrots
- Apple
- Nuts
- Dressing
Instructions
- Put the nuts (walnuts, sunflower, sesame, etc) in a small frying pan on the stove on medium high heat.
- Chop up the kale, cabbage, apple, and carrots as fine as you can. The smaller the better.
- At some point during all that chopping you'll start to smell the nuts. Give them a little shake in the pan and let them go for a bit longer. You're hoping for a light browning.
- Throw each thing into a big bowl as you get them chopped up, and then add the dressing. My preference is Annie's Goddess Dressing with a little Hot Pepper Sesame Oil for flare, but just follow your heart. Mix the dressing in and then sprinkle the roasted nuts on top.

Fitting In With The New Cool Kids
For the past few weeks, I've had the opportunity to work on my website out of the illustrious offices of Stack Exchange (commonly confused by almost everyone I've told this to, with the "Stock Exchange" - no, mom, no). Stack Exchange created Stack Overflow, which is THE Go-To Question and Answer site for developers. The company also built a few other spin-off Q&A sites (not focused on coding) using the same model.Why am I able to chill at/take advantage of on-sight chefs/ping pong tables at Stack?
Because they participate in a program called The Fog Creek Fellowship. Fog Creek (another software company with which Stack shares a co-founder) started the fellowship after having noticed that only 14% of their developer applicants were women and that all of their current developers were male.
Brainstorming ways to overcome this lack of diversity, they decided to allow select female graduates of the Flatiron School (an intensive 12-week coding course from which I graduated) to have 8 weeks of access to space at their offices and a mentor. The mentors "...help fellows prepare for coding interviews, offer assistance comparing offer packages, build confidence, and help create long-lasting professional relationships."
So, with no cost on my part, I get all the stuff mentioned above. And my mentor Jon Chan, a brilliant developer and creator of Bento, has been nothing but supportive and awesome (and has really helped me with my website from both a technical and business standpoint).
What has also been invaluable is having the opportunity to observe this world for the first time. The only office culture I'd engrossed myself in previously was the small management consulting firm I'd worked at -old-school, finance - need I say more?
And although the Flatiron School (FIS) is a developer community as well, it didn't exactly paint a picture of what the professional community is really like. FIS trains non-developers to be developers and so our class was not really representative- we were more than 50% women - and people used to do all sorts of things before joining the school - consulting, finance, HR, teaching. Thus, my sense of who developers were was kind of skewed.
In contrast, many of the developers at Stack and Fog Creek/Trello, to put it bluntly, are the cliché.
Between Fog Creek and Stack, 2 of the dozen or so mentors got kicked out of school for hacking computers. They're all male and many wear glasses. And Stack has not 1, but 2 video game stations...
And the office- well...it's amazing - I'd had the opportunity to visit Google as well and this was like a mini-version. We've all seen articles in Business Insider or Gawker about how Facebook has nap rooms and video games but somehow, it's not really real until you see it for yourself. My jaw still has not reattached itself to my face- why isn't every office like this!! - how did I work in finance so long? -unlimited snacks, beers, 2 chefs (1 dedicated solely to pastries) who cook gourmet lunches everyday.
Despite not knowing what it's like to actually work for one of these places, there are a few things you can just see. People at Stack (developers and non developers) are open, happy, and excited about what they are accomplishing. Being there has made me rethink what a business is and made me more excited about being a web developer- someone who actually builds things that add value to people's lives. I'm very lucky to get this insider look into what the world of tech can be, and instead of working on my golf game... X-Box all the way.

Subject: RE: 2002 Aviation budget
Use $4,800 so there will be no surprises. That includes fixed and variable.
The budget has not been approved yet, there could be an increase, but I feel confident with the $4,800 estimate.

Subject: RE: 2002 Aviation budget
Caroline, What I been told is the following:
$3,775/hr fixed costs plus variable costs associated with specific trips i.e. fuel, landing fees, catering etc.
Typically I think an average per hour cost of $4,500 is used.
Gary, Does this sound reasonable for budgeting purposes?

Subject: 2002 Aviation budget
For the 2002 Plan NNG will budget aviation by function i.e commercial, operations etc. Therefore each functional area needs to assess their company plane usage and budget accordingly for 2002.
Gary, Once we have rolled each functional area up to the NNG legal entity level we will be able to provide you with the total NNG aviation budget for 2002.

Overview
Things to know when using the popover plugin:
- Popovers rely on the 3rd party library Popper.js for positioning. You must include popper.min.js before bootstrap.js or use
bootstrap.bundle.min.js
/bootstrap.bundle.js
which contains Popper.js in order for popovers to work! - Popovers require the tooltip plugin as a dependency.
- If you’re building our JavaScript from source, it requires
util.js
. - Popovers are opt-in for performance reasons, so you must initialize them yourself.
- Zero-length
title
andcontent
values will never show a popover. - Specify
container: 'body'
to avoid rendering problems in more complex components (like our input groups, button groups, etc). - Triggering popovers on hidden elements will not work.
- Popovers for
.disabled
ordisabled
elements must be triggered on a wrapper element. - When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors’ overall width. Use
white-space: nowrap;
on your
s to avoid this behavior. - Popovers must be hidden before their corresponding elements have been removed from the DOM.
Keep reading to see how popovers work with some examples.
Example: Enable popovers everywhere
One way to initialize all popovers on a page would be to select them by their data-toggle
attribute:
Example: Using the container
option
When you have some styles on a parent element that interfere with a popover, you’ll want to specify a custom container
so that the popover’s HTML appears within that element instead.
Example
Four directions
Four options are available: top, right, bottom, and left aligned.
Dismiss on next click
Use the focus
trigger to dismiss popovers on the user’s next click of a different element than the toggle element.
Specific markup required for dismiss-on-next-click
For proper cross-browser and cross-platform behavior, you must use the
tag, not the <button>
tag, and you also must include a tabindex
attribute.
Disabled elements
Elements with the disabled
attribute aren’t interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you’ll want to trigger the popover from a wrapper

or
and override the pointer-events
on the disabled element.
For disabled popover triggers, you may also prefer data-trigger="hover"
so that the popover appears as immediate visual feedback to your users as they may not expect to click on a disabled element.
Usage
Enable popovers via JavaScript:
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-
, as in data-animation=""
.
| Name | Type | Default | Description |
|---|---|---|---|
| animation | boolean | true | Apply a CSS fade transition to the popover |
| container | string | element | false | false |
Appends the popover to a specific element. Example: |
| content | string | element | function | '' |
Default content value if If a function is given, it will be called with its |
| delay | number | object | 0 |
Delay showing and hiding the popover (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: |
| html | boolean | false | Insert HTML into the popover. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks. |
| placement | string | function | 'right' |
How to position the popover - auto | top | bottom | left | right. When a function is used to determine the placement, it is called with the popover DOM node as its first argument and the triggering element DOM node as its second. The |
| selector | string | false | false | If a selector is provided, popover objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added. See this and an informative example. |
| template | string | '

' |
Base HTML to use when creating the popover. The popover's The popover's
The outermost wrapper element should have the |
| title | string | element | function | '' |
Default title value if If a function is given, it will be called with its |
| trigger | string | 'click' | How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space. `manual` cannot be combined with any other trigger. |
| offset | number | string | 0 | Offset of the popover relative to its target. For more information refer to Popper.js's offset docs. |
| fallbackPlacement | string | array | 'flip' | Allow to specify which position Popper will use on fallback. For more information refer to Popper.js's behavior docs |
| boundary | string | element | 'scrollParent' | Overflow constraint boundary of the popover. Accepts the values of 'viewport' , 'window' , 'scrollParent' , or an HTMLElement reference (JavaScript only). For more information refer to Popper.js's preventOverflow docs. |
Data attributes for individual popovers
Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.
Methods
Asynchronous methods and transitions
All API methods are asynchronous and start a transition. They returns to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.
$().popover(options)
Initializes popovers for an element collection.
.popover('show')
Reveals an element’s popover. Returns to the caller before the popover has actually been shown (i.e. before the shown.bs.popover
event occurs). This is considered a “manual” triggering of the popover. Popovers whose both title and content are zero-length are never displayed.
.popover('hide')
Hides an element’s popover. Returns to the caller before the popover has actually been hidden (i.e. before the hidden.bs.popover
event occurs). This is considered a “manual” triggering of the popover.
.popover('toggle')
Toggles an element’s popover. Returns to the caller before the popover has actually been shown or hidden (i.e. before the shown.bs.popover
or hidden.bs.popover
event occurs). This is considered a “manual” triggering of the popover.
.popover('dispose')
Hides and destroys an element’s popover. Popovers that use delegation (which are created using the selector
option) cannot be individually destroyed on descendant trigger elements.
.popover('enable')
Gives an element’s popover the ability to be shown. Popovers are enabled by default.
.popover('disable')
Removes the ability for an element’s popover to be shown. The popover will only be able to be shown if it is re-enabled.
.popover('toggleEnabled')
Toggles the ability for an element’s popover to be shown or hidden.
.popover('update')
Updates the position of an element’s popover.
Events
| Event Type | Description |
|---|---|
| show.bs.popover | This event fires immediately when the show instance method is called. |
| shown.bs.popover | This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.popover | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.popover | This event is fired when the popover has finished being hidden from the user (will wait for CSS transitions to complete). |
| inserted.bs.popover | This event is fired after the show.bs.popover event when the popover template has been added to the DOM. |


Lecture IV - Supervised Learning
The goal for this lecture is to familiarize the students with some of the basic supervised machine learning algorithms and the care that must be taken in their application applications. In particular:
Sept 7, 2017 - 12:15-13:10
- Regression vs Classification
- Overfitting
- Bias-Variance Tradeoff
- K-Nearest Neighbors
- Validation dataset
- Perceptron
- Activation Functions
- Back Propagation
- Support Vector Machines
By the end of the lecture the students will understand some of the fundamental supervised machine learning algorithms.


Programmers may declare new named data structures with the following procedure:
:- foreign_type Type_name = Type, ..., Type_name = Type.
where Type_name is an atom, and Type defines either an atomic or compound type, or is a previously-defined type name.
In Prolog, atomic types are represented by the natural atomic term
(integer, float, or atom). Compound structures are represented by
terms whose functor is the name of the type, and whose only argument
is the address of the data. So a term foo(123456)
represents the
thing of type foo
that exists at machine address 123456. And a term
integer(123456)
represents the integer that lives in memeory at
address 123456, not the number 123456.
For types that are not named, a type name is generated using the names of associated types and the dollar sign character (`$'), and possibly a number. Therefore, users should not use `$' in their type names.

Got it!


importance: 5
Here’s a code that asks the user for two numbers and shows their sum.
It works incorrectly. The output in the example below is 12
(for default prompt values).
Why? Fix it. The result should be 3
.
```js run let a = prompt(“First number?”, 1); let b = prompt(“Second number?”, 2);
alert(a + b); // 12 ```


Code of Conduct
What is this code of conduct for?
Appium is a piece of technology, but the core of the Appium community is the people in it. As such, we are committed to providing a friendly, safe and welcoming environment for all, regardless of gender, gender identity and expression, sexual orientation, ability, physical appearance, body size, race, age, socioeconomic status, religion (or lack thereof), or other marginalized aspect of comunity members. We expect all members of the Appium community to abide by this Code of Conduct whenever interacting in Appium venues (pull requests, GitHub issues, 1-1 or group chat, meetups, conferences, etc…)
Examples of inappropriate behavior
Because we come from a variety of backgrounds, we don’t want to assume that everyone has the same assumptions about what is and isn’t appropriate. Here are some examples of inappropriate behavior that are incompatible with our community’s ethos:
- Spamming, trolling, intentionally disrupting conversations, or irrelevant solicitation or advertisement
- Making demeaning or discriminatory comments
- Making negative assumptions about someone’s background, abilities, or intentions
- Harassing or stalking individuals (online or in person)
- Giving someone unwelcome sexual attention or making unwelcome physical contact (in the case of an IRL event)
- Sharing sexual images or using sexually explicit language
In general: treat others how you would like to be treated, were you in their place.  Do ask questions. Do keep conflicts productively focused on technical issues. Do think before you speak; remember that what is perceived as a funny witticism in your group of friends might be hurtful or reinforce hurtful stereotypes in the context of our diverse online community. Do remember that we are all people, not robots, and all equally deserving of sensitivity and respect. (If and when robots join our community, let’s treat them with respect too!)
What will organizers do about inappropriate behavior?
If we notice you doing or saying something inappropriate, an organizer will explain why it’s inappropriate and ask you to stop. We won’t demonize or vilify you. But please do stop the inappropriate behavior so we can get back to writing and discussing code in a safe environment. If you have philosophical disagreements about what’s actually inappropriate, please take them to a separate public or private conversation with an Appium maintainer so we don’t turn pull requests into an ethics debate.
If you keep doing unacceptable things, we’ll likely ban you, report you to GitHub, or take other appropriate action.
What if I see or am subject to what feels like inappropriate behavior?
Let us know! Please notify a community organizer as soon as possible. Full contact information is listed in the Contact Info section of this document. All communications will be kept strictly confidential, unless otherwise required by law. No issue will be considered too inconsequential or unimportant for us to have a conversation about.

If you need to report an incident, please contact any of the following organizers directly:

Karan Patel confirms promo shoot of ‘YHM’ spin-off show ‘Yeh Hai Chahatein’
by BizAsia CorrespondentKaran Patel has confirmed that the promo shoot of Star Plus’ upcoming series ‘Yeh Hai Chahatein’ has taken place, in which the new leads of the show Abrar Qazi and Sargun Kaur Luthra, will be unveiled.
‘Yeh Hai Chahatein’ is the spin-off series of ‘Yeh Hai Mohabbatein’ and is expected to launch in December. Rumours are rife that ‘Yeh Hai Chahatein’ will replace ‘Yeh Hai Mohabbatein’. It is also speculated that Patel will be reprising his role as Raman, as a part of the show’s ending storyline.
Where Tripathi Dahiya shared an image with Patel on her Instagram, Patel confirmed the news about the promo shoot by saying, “Yes, we have shot a promo with the female lead of Yeh Hai Chahatein but I can’t reveal the details about the same.”

AMT |
(powder / crystals) |
Its now saturday morning, I'm still tripping off a dose of amt I took at 9 last night, 15 hours so far and its been great.
I got a few doses of amt from a friend of mine which came in the form of a putrid smelling powder, I put a few doses in gel caps and took 1 at around 9 on friday night with a friend. I had skipped dinner because i heard you can get nausa and stomach discomfort, so all i had eaten was a sandwhich at about 1 o'clock that day.
Within the first hour I could begin to feel the effects, slight upset stomach, but it went away as quickly as it came. Starting with the second hour and going on the whole trip a general sence of euphoria was strong. What ever music was playing was great to listen to. Although I could feel the euphoria my general mental state was mildly tripping, but clear headed, no visuals yet. At this point the setting is a bumping party, contrary to what i read on some of the trip reports, amt is an exelent recreational drug!!
Once 4 oclock rolled around (T+7) we decided to smoke some weed. This was probably the best thing we couldve done, the synergy between the amt and the weed worked soo amazingly together. Within minutes after smoking I got intense visuals, not so much closed eye, but amazing open eye hallucinations. I have tripped off acid a few times before, but never got visuals like I did with the amt. From the point we smoked weed till around 4 hours later the peak of my trip was being experienced. At some points I would just be looking at the tile floor melt and move around, then all of a sudden I felt like I was rolling. I got the strong euphoria and even the eye jiggles. Although its still not done yet I would rate my amt experience as the best drug experience I've had. Although very close in second would have to be rolling.
Overall this trip has been really good.   This is not the kind of drug i try just by myself, cause when your tripping 15+ hours its good to have someone else whos going through the same thing.
This is especially true if the amt is taken at night, because when its 7 oclock the next morning and your still tripping balls, many people who arent on it will pass out, so this way youll have some company. This is definaltly something i would like to do again, probably the same dose...but not for a while. Even though I've had a great time the whole way through, tripping 18 hours can take a toll on you, so i'd wait a while before i tried it again.
