Saturn is the second largest planet in the solar system. It has a "Great White Spot" that in fact isn't an actual spot but instead are storms that occur approximately every 28.5 years.

Bismuth-209, the most stable isotope for Bismuth, is so stable that not until 2003 was it discovered that it was actually radioactive. It's half-life is 4.6x10^19 years.

Reflection can be modeled with an Oren-Nayar Model and doesn't happen at Brewster's angle. The reason why cats' eyes glow is because of the retro version. When the angle is above the critical angle, Total Internal Reflection (TIR) occurs. Fiber optics is an example of an application of TIR.

Formaldehyde (CH2O) is the simplest aldehyde. An elimination reaction with phenol will make Bakelite, a synthetic plastic. If you oxidize it, you can get formic acid, an acid found extensively in nature like in ants. Historically it has been used to preserve the remains of organisms.

Saturn is spinning and wiggling at the same time, and these times are synched so it makes a hexagon. It's suprisingly common.

Sengoku Jidai was a roughly 110 war in that happened in 15th and 16th century Japan. It was one of the biggest wars in Japanese history, as well as the first to have the use of firearms thanks to Portuguese missionaries and traders.

Boil some water in a pot (without a bunch of scratches/marks) on the stove some time. Give it a little shake. Notice what shape the bubbles make?

I think he meant "110-year-long war"

As in, "Sengoku Jidai was a roughly 110-year-long war that happened in 15th and 16th century Japan"

Ethanol is an alcohol with two carbons. USA and Brazil are the top producers of the substance. The bacterium Clostridium thermocellum can convert lignocellulose into ethanol by decomposing glucose.

Specific heat is energy needed to raise 1g of substance by 1K. It is about 4.184 J/(K*g) for water. It can be measured with a "bomb" calorimeter. The molar specific heat for metals usually follow the Dulong and Petit law which approximates the specific heat to be around three times the ideal gas constant.

One cup of tap water has approximately one drop of deuterium in it.

If fused, this one drop would release the energy equivalent of 20 gallons of gasoline.

Total global funding for fusion research: about $1.5 billion per year.

Gross earnings for the film Avatar: $2.8 billion.

The Rosetta Stone is made of basalt and was found in 1799 by Napoleon's troops near Alexandria, Egypt. It had ancient Egyptian hieroglyphics in addition to Greek language. Thomas Young and Jean Champollion are credited with deciphering the Rosetta Stone. To those that don't recognize, Thomas Young also conducted the famous double-slit experiment establishing the wave-particle duality.

Carl Friedrich Gauss is a very famous mathematician. His work and fame was received with much accolades that a unit of magnetic field strength is named after him. While a teenager, he proved that one could construct a heptadecagon (17 sides) with just a compass and straightedge by exploiting the fact that 17 is the second Fermat prime. He is also attributed with developing modular arithmetic among many other things.

If you were to get all the neutrons, protons and electrons in your body and condense it down so they were touching, you would be the size of a grain of sand

A magnetic field is symbolized as 'B'. Using Ampre's law one can relate it to electric current. A constant magnetic field can cause spectral lines to split up by the Zeeman effect. In certain strong fields, it would the Paschen-Back effect. The Stark effect would be an analogous explanation for the spectral split by an applied electric field.
