Got my #FREE #Prescription #Glasses from #clearlycontacts ! Lookin’ extra #nerdy with #Einstein on the background :P
Einstein’s matriculation certificate at the age of 17, showing his final grades from the Aargau Kantonsschule.
Richard Feynman was damn witty. He once noted that he wished to memorize Pi all the way up to the 762nd place, because at that point begins a series of six nines in a row.
The Feynman Point, highlighted in red, was amusing for him so that he could recite the digits up to that point, and then say “nine-nine-nine-nine-nine-nine and so forth,” thus implying that Pi was rational.
How to Easily Memorize e to Fifteen Decimal Places
See that picture? It’s a 20 dollar bill, so “2” is the first digit - throw down a decimal after it.
Andrew Jackson was our seventh President, so put a “7” after that - 2.7
Jackson was elected in 1828, so put down “1828″ next. Since he served two consecutive terms, put “1828″ a second time. We’re now up to 2.718281828.
Now pay attention to the red square. The diagonal creates two congruent right triangles with angle measures 45, 90, and 45. So, add on 459045 to get 2.718281828459045. And that’s e to 15 places.
That’s one person I’d like to be able to draw.
String Theory is a current hot topic amongst Physicists, but what exactly is it? The most straightforward way to describe it is to think of a guitar string. Depending on how much tension is in the spring and how it’s plucked, a different vibration pattern and thus a different sound results.
Similarly, string theory says that subatomic elementary particles can be thought of as nearly infinitesimally small strings exhibiting their own “musical notes,” known here as excitation modes. These strings are about 10-33 cm, or about a millionth of a billionth of a billionth of a billionth of a centimeter in length. These vibrating strings are floating around in space-time, experiencing tension. In essence, there are two types of strings:
There are two basic types of string theories: those with closed string loops that can break into open strings, shown above, and those with closed string loops that can’t break into open strings, shown below
While there small size is fascinating, it makes actually seeing and determining the existence of these strings extremely difficult. Since the strings are far too small to actually see, Physicists must be clever in devising ways to determine if the strings are there.
