العقد المنسي؟
يقال عن الأحداث اللتي وقعت في الفترة مابين عام 1960 إلى 1969 أنها وقعت في ستينيات القرن وعن الأحداث اللتي وقعت الفترة مابين عام 1970 إلى 1979 أنها وقعت في سبعينيات القرن….وهكذا. ماذا عن الأحداث التي وقعت في الفترة من 1900 و حتى 1909؟ أو 2000 و حتى 2009؟؟ لم أسمع أي تسمية لهذه الفترة…. هل لها تسمية وحضرتنا لسنا على إلمام بها؟ أم أنها سقطت سهواً أو حتى عمداً؟

What’s with the H?

In the world of Science,
V is the volume,
Z is the partition function,
P and Q are the position and momentum of a particle.
R is the gas constant,
and T is temperature.
W is the number of states,
and we have to keep X and Y in case
we need more variables…
Going back to the first half of the alphabet:
A, F, and G are for free energies,
B is a magnetic field.
I is the symbol for information;
J and L are angular momenta.
K is Kelvin, which is the proper unit of T.
M is magnetization,
and N is total number of elements,
O is too easily confused with 0….
This leaves S, and H.
S is for Sets..
Thus, H is for Entropy !!

Move over RedBull The No-Sleeping Pill is here
Modafinial is usually prescribed to treat a medical condition that causes excessive daytime sleepiness, but other people have discovered other benefecial uses of it, such as people who are leading very busy lives who don’t have enough time for a full night’s sleep. Just take one before you go to bed and get 4-5 hours or whatever your time permits, and wake up all refreshed and ready to go!! Unlike energy drinks and other caffein type drinks modafinil does not cause sudden drop of energy later on. Neither do you have to make up for the sleeping time you missed on consecutive nights, becasue it is simply not an energy drug, it doesn’t affect your energy nor does your focusing becomes any higher, you just wont feel the need to sleep … -how smart it that!-
NewScientist has an article about the drug, it describes it as “Modafinil is just the first of a wave of new lifestyle drugs that promise to do for sleep what the contraceptive pill did for sex – unshackle it from nature“
I know what I would do if I can get my hands on a prescription – what would you do in your extra awake time? spend more time with your kids? finally have time to excrcise? or beat your friends record of watching 13 movies in a row?
