$250,000 for a High School Science Regression to the Mean 2 days ago   11:48

The story of three impressive high school science projects. Can you guess which student won $250,000 in the #RegeneronSTS? Applications open June 1: http://bit.ly/2HkLXT1 This video was sponsored by Regeneron. The Science Talent Search was founded and produced by the Society for Science and the Public.

Huge thanks to the students: Ronak Roy, Ana Humphrey, and Anjali Chadha. It was great getting to meet all of you and learn about your original scientific research.

Special thanks to Assistant Professor Konstantin Batygin for discussing Ana's research and Planet 9 with me. More is coming on the Planet 9 front.

Ronak came up with a new design for the phoropter, the device used to determine eye-glass prescriptions. It's basically been unchanged for 200 years. Using a liquid lens, he miniaturized the device and wrote an algorithm to determine your prescription.

Ana used math and physics to search for hidden exoplanets. There are a number of reasons why the transit method and Kepler telescope may have missed them: they're too small, too inclined, or take too long to orbit and so were not seen. By considering which planetary systems have additional space for more planets, Ana came up with 560 locations where we may look again for planets in future.

Anjali developed an internet enabled device for measuring arsenic concentrations in drinking water. The device performs several chemical reactions to release the arsenic into a measurable state. It then reacts the arsenic with a test strip to produce a color output. This color is sampled by a camera and processed to determine the concentration of arsenic in the water sample. This has significant potential applications around the world helping reduce exposure to arsenic and potentially other contaminants.

Wait. I mean the app and apparatus is impressive enough but did he engineer that liquid lens himself or was it existing technology that has been re-purposed?

Dang 1st and last one are Indian.

All three of these kids are geniuses in their own right, but I would be very surprised if the winner wasn't the kid who reinvented the eye test.


Edit* I am surprised

Shoutout for Anna!

They are obviously all good, but it's true she looks completely moved by what she's doing, so passionate, but also so straight to the point and sharp. Amazing work!

I will not be the one who dicedes who of all the clever people are win the price. Its look a little bit unfair to all other.

Can somebody explain me Ana Humphrey's formula????
Tim Lapp
All about the practicality

All of the three had some fantastic projects, and I'm quite surprised (pleasantly so) that the one with the least immediate commercial utility is the one that got the prize. In these high competition situations that's often a deciding factor, to my knowledge...
Little edit, I had placed my votes on the third candidate, the lady with the water purity checker thing. It seems like the kind of thing companies, researchers and goverments would be scrambling all over to get, if it's a cheaper or more efficient solution than what's currently available :)

Pffff weaklings, i watch rick and morty and i have an iq of 250

Anjali Chaa daa doesn't know how to pronounce her own name.

No offence but the gravity one was the only one that was actually ground breaking. The rest used pre-existing hardware and re-invented the wheel. Don't understand how that's worth of $25,000

This is amazing, but also at the same time remember, calculus was founded by a highschool/college level student as well.

That water filter thing was lame weak expensive toy

Why are they no whites? Has this contest been closed to whites and only opened to poc and jews?
Happyme!
Have you gone to a few opticians to compare what they say to the machine/app result?

Never thought I'd see Matlab in two popular videos within a couple of months...

Why did the one judge guy not want to shake hands but touch elbows instead?

My question is how do they even find does problems to start with???

Regression to the Mean $250,000 for a High School Science 2 days ago   07:38

Is punishment or reward more effective as feedback? Do new medical treatments really work? What about streaks in sport? Without considering regression to the mean, we are prone to making significant errors.

Is punishment or reward more effective for helping people learn. A lot of people would say different incentives motivate different people, or in different circumstances, but in psychology there is a sizable body of evidence that in order to learn skills, positive feedback is more effective. This fining has been verified not just with humans, but also with other species.

It was strange then that after Daniel Kahneman discussed this research with Israeli fighter pilot instructors that he was met with resistance. They found the opposite was true: when they reprimanded a cadet for performing poorly, he invariably improved, but if they praised a cadet for an excellent performance, the next attempt was not as good. In order to solve this apparent contradiction we first need to understand regression to the mean.
