Phascinating physics.............

Did you know that if you have two straws, one in your mouth and one inside of a cup filled with a drink, no matter how hard you try, you will not be able to drink from either straw.  That is physics!

Physics is all about studying matter and energy in space and time and how they interact with each other.  Physics is also an experimental science.

The word physics comes from the Greek word that means nature.

Energy can be gravity, motion, light, electricity, and/or radiation.

Phun phactoids for physics:

Sir Isaac Newton discovered the laws of motion and gravity in 1687.

Albert Einstein is noted to be the most famous physicist ever.  He won the Noble Prize in Physics for theoretical physics.  On a side note, Einstein is also the co-inventor of the refrigerator.

The lowest energy of an atom is called ground state.

Did you know that sunlight exerts solar radiation pressure?  It does and on a clear day sunlight can be reflected off of a mirror that can be seen 25 miles away.  Crazy!

Light travels about 900,000 times faster than sound travels.

Sounds travels 767 miles per hour.

X-rays are another form of physics.  Wilhelm Conrad Rontgen produced and detected electromagnetic radiation in a wavelength in 1895.

Atoms are 99.999999999999% empty space and believe it or not, all the matter that makes up the human race can fit on a sugar cube.

The mass of our atmosphere is 5.500,000,000,000,000 (quadrillion).

Venus is the only planet that spins in the opposite direction to Earth.

Uranus is the only planet that rolls on its side like a barrel.

If you were somehow on Mars and trying to weight yourself for some unknown reason, because of gravity, your weight would be significantly lower.  For example, if you weigh 200 pounds on earth that translates to about 76 pounds on Mars.

Light from earth takes only 1.255 seconds to reach the moon.

Israel is the lowest location on earth (400 meters below sea level).  The ever famous Dead Sea is located there.    The Dead Sea is so dense with salt water (hypersaline), you can actually float on it.

Crazy!  Cosmonaut Sergie Avdeyev was in space for 747 days and when he returned, he was one fraction of a second younger.

Alchemy of diamonds.  Turns out you can convert graphite into diamonds by applying a temperature of 3000 Celsius and a pressure of 100,000 atm.  I need to try this!

If you throw a tennis ball in space, it would just keep moving in a straight line with the same speed forever!  This is because space has no resistance to motion.

Pretty interesting stuff physics.  Follow the links to learn more.
