MIT is the Massachusetts Institute of Technology, largely regarded as one of the top universities in the world.


For context:

This is the third post in a series. The author (Jason Scott) is trying to save ~25,000 manuals, instruction booklets, and engineering notes (largely electronics related, created over the last 80 years). This is a large project, the company which owns the manuals currently is going out of business, and all the manuals will be thrown away very soon (re: tomorrow).

It is infeasible (IMHO) to deal with all physical manuals ever in this way, unless you are literally a Manuals Library that is supported by the county or whatever.

I think the only way to go forward is to digitize the shit out of everything.

>Function names should be lowercase, with words separated by underscores as necessary to improve readability.


"On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question." -Charles Babbage


Mars One intends to land its first crew on Mars in 2025. http://www.mars-one.com/mission/roadmap


In the realm of the feasible, SpaceX plans to land people on Mars in about 25 years.


For a function to be a linear transform it needs two properties[1]:

  1. F(c1 + c2) = F(c1) + F(c2)
  2. F(k*c1) = k*F(c1)
Converting from Celsius->Fahrenheit (or vice versa) is does not have these properties.

  F(c) = 9/5 * c + 32

  F(c1 + c2) = 9/5 * (c1 + c2) + 32
  F(c1) + F(c2) = (9/5 * c1 + 32) + (9/5 * c2 + 32) = 9/5 * (c1 + c2) + 64

  F(k*c1) = 9/5 * (k*c1) + 32
  k*F(c1) = k * (9/5 * c1 + 32) = 9/5 * (k*c1) + k*32
Admittedly, I'm not entirely sure why being a non-linear transform gets the OP so riled up.

" Admittedly, I'm not entirely sure why being a non-linear transform gets the OP so riled up."

Because it's harder to calculate mentally

One can approximate 2lb to 1kg roughly, 1mi ~ 1.6km, but for Fahrenheit this is harder

One solution is to establish a set point ( 70F = 21.1C, approximate to 20C ) then work in differences, since 1.8deltaF = 1deltaC so, 2dF ~ 1dC (or 10dF ~ 5dC)

Hence, 90F is approximately 30C (exact value, 32.2C)


The FSI[1] has ranked languages according to how easy it is for English speakers to learn. There are 10 languages in Category I (the easiest to learn)[2]:

Afrikaans, Danish, Dutch, French, Italian, Norwegian, Portuguese, Romanian, Spanish, Swedish

I would suggest checking out index funds from Vanguard (or Fidelity or Schwab).

Also, you may want to post this to: http://www.reddit.com/r/personalfinance/

They're a very reasonable and helpful community.
