Lev Bulat

Lev Petrovich Bulat (Russian: Лев Петрович Булат; 1947–2016) was a Russian physicist.

Bulat was born on April 11, 1947, in Chernovtsy, Ukraine. In 1988 he received a D.Sc in Physics and Mathematics, from Leningrad Polytechnical Institute, with the thesis: "Transport Phenomena in Semiconductors under Large Temperature Gradients".

He was an expert in transport properties of semiconductors, physics of nanostructures, thermoelectric phenomena, direct energy conversion, thermoelectric cooling. He was a Professor of electrical and electronic engineering in Saint Petersburg State University of Low Temperatures and Food Engineering, Russia.

He died suddenly on June 12, 2016, age 69, less than two weeks after attending an international conference.^[1]

All through elementary school and high school you grow up hearing about the flat earth we live on and doing boring flat-earth physics homework and then (if you're lucky enough) you get to college and PSYCH! \f1 for the first time they show you a globe and say "sorry for lying, the earth is actually round".\ \ Well, this is, unfortunately, exactly what we do with\ \ 1) Gravity\ You probably learned that objects attract each other based on their mass so you probably grew up thinking that light can't possibly be affected by gravity because light is massless. I know I did. Well guess what? The source of gravity is not mass - it's energy and momentum, which light certainly has (of course, regular matter does too). So not only does light get bent passing by a star or planet or black hole, but light attracts the planet or star or black hole in return (to be sure, it's only a very very small amount. But a small amount is not zero). Anyway, the point is that Newton's law of gravitation is just an approximation - good enough to get us to the moon, but not perfect. General relativity is better.\ \ 2) Special Relativity\ Speaking of the moon, you probably also learned that if a sheep is moving 2 mph relative to a train and that train is moving 2 mph in the same direction relative to the ground, then the sheep is moving four mph relative to the ground. 2mph+2mph=4mph, right? FALSE. Experiments in special relativity have confirmed that velocities don't simply add together and so the sheep will in fact be moving very very ever-so-slightly slower than four mph relative to the ground. And the formula that correctly predicts this deviation from just adding the velocities is (v1+v2)/(1+v1*v2/c^2). It's not a very big effect, but then again, the earth looks pretty flat, doesn't it?\ \ But the earth isn't flat: if I walk 10,000km away from my cat, and you continue on walking 10,000km more, you're NOT 20,000km away from my cat. You're just 12,750km away\'85 in fact, the farthest on earth you can get from ANYTHING on earth is 12,750km. It's the "earthly distance-limit", though we normally call it the diameter of the earth. And similarly, when you try to add two velocities together, there's a "cosmic speed limit" of 300,000,000m/s - that is, the speed of light.\ \ So, just because to our eyes the earth looks flat, velocities look like they simply add together, and light looks like it doesn't attract gravitationally, is that an excuse to mislead ourselves and our children about the true nature of things?}
