Water Margin quote Updated +Created
Something along:
If two men are destined to meet, they will come together from thousands of miles apart. If they aren't, they will pass by in front of one another and never know about one another's existence.

How to teach / Showcase student work Updated +Created
The thing about projects is that they are illiquid: it is not easy to immediately compare them.
And that is the whole point.
The outcome of that however is that you have to learn how to explain what you've achieved to others and why it is awesome.
Just like in the real world.
You have to create portfolio, and do some public relations.

The Honourable Schoolboy Updated +Created
We need a TV adaptation of this, urgently!!!
en.wikipedia.org/wiki/The_Honourable_Schoolboy#Adaptations mentions:
Jonathan Powell, producer of Tinker, Tailor, Soldier, Spy (1979), said the BBC considered producing The Honourable Schoolboy but a production in South East Asia was considered prohibitively expensive and therefore the BBC instead adapted the third novel of the Karla Trilogy, Smiley's People (1979)
Bohr-Sommerfeld model Updated +Created
Refinement of the Bohr model that starts to take quantum angular momentum into account in order to explain missing lines that would have been otherwise observed TODO specific example of such line.
They are not observe because they would violate the conservation of angular momentum.

The fact that you cannot have trailing commans in lists or dicts as in 3, at:
{
  "asdf": [
    1,
    2,
    3,
  ]
}
is one of the most infuriating design choices of all time!!!

Rat Updated +Created
Since rat and mouse are not scientifically specific names, we'll just use them interchangeably.
When one specific species is implied, we will mean Mus musculus by default.

2009 Nobel Prize in Physics Updated +Created
This one took a while! Major developments were from the 70s! Perhaps it took the Internet revolution to make its importance clear.
Boltzmann constant Updated +Created
This is not a truly "fundamental" constant of nature like say the speed of light or the Planck constant.
Rather, it is just a definition of our Kelvin temperature scale, linking average microscopic energy to our macroscopic temperature scale.
The way to think about that link is, at 1 Kelvin, each particle has average energy:
per degree of freedom.
This is why the units of the Boltzmann constant are Joules per Kelvin.
For an ideal monatomic gas, say helium, there are 3 degrees of freedom. so each helium atom has average energy:
If we have 2 atoms at 1 K, they will have average energy , and so on.
Another conclusion is that this defines temperature as being proportional to the total energy. E.g. if we had 1 helium atom at 2 K then we would have about energy, 3 K and so on.
This energy is of course just an average: some particles have more, and others less, following the Maxwell-Boltzmann distribution.
Crystal radio Updated +Created
This was the first generation of commercially successful radios.
It uses a crystal detector as its diode, which is a crucial element of the radio, thus its name.
They were superseded by transistor radios, which were much more reliable, portable and could amplify the signal received.
