A Harshad number is a positive integer which is divisible by the sum of its digits. For base 10 there is no sequence of more than 20 consecutive Harshad numbers.
Dirac's equation
In 1928 Paul Dirac wrote down this simple equation that predicts the existence of antimatter particles. He postulated the existence of positively charged electrons - the positrons - which were experimentally discovered in 1932 by Carl Anderson.
"A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street" - David Hilbert
This is the “Standard Model Lagrangian”.
It is an equation that encapsulates just about everything we currently know about particle physics.
Most folks never see it, now you have.
The #Ax1 crew just walked down the crew access arm to the white room. They underwent extensive training to prepare for these final moments. Their hard work and dedication will soon come to fruition as they ingress into the spacecraft.
Richard Feynman found trigonometry notation to be ambiguous and confusing.
"If I had sin f, it looked like s×i×n×f"
So he decided to create his own notation. See below. 🧐
What do you think?
"The nine Indian figures are:
9 8 7 6 5 4 3 2 1
With these nine figures, and with the sign 0 which the Arabs call zephir any number whatsoever is written"
Leonardo Fibonacci popularized the Hindu–Arabic numeral system in Europe with his book Liber Abaci published in 1202.
