  • Non-Euclidean geometry was developed by pure mathematicians who were trying to prove the parallel line postulate as a theorem. They realized that all of the classic geometry theorems are all different if you start changing that postulate.

    This led to Riemannian geometry in 1854, which back then was a pure math exercise.

    Some 60 years later, in 1915, Albert Einstein published the theory of general relativity, of which the core mathematics is all Riemannian geometry.








  • Legally speaking, this was a victim impact statement.

    Convicted criminals have long had the common law right of allocution, where they can say anything they want directly to the judge before sentence is passed.

    Starting a few decades ago, several states decided that the victims of crime should have a similar right to address the judge before sentencing. And so the victim impact statement was created.

    It’s not evidence, and it’s not under oath, but it is allowed to influence the sentencing decision.

    (Of course, victim impact statements are normally given by real victims).






  • As an earthling, you have evolved over the course of billions of years to deal with sunlight at a distance of one astronomical unit. That’s the distance of the earth’s orbit. That’s probably the most comfortable distance.

    The Apollo moon missions used a so-called “barbecue” mode that rotated the capsules at three revolutions per hour. They did this during the 3-4 day coast phases to and from the moon. As far as I know this was able to mostly hold the interior temperatures in the “survivable” range.







  • The critical document in this story is the BOE, but I have no idea what that’s supposed to stand for.

    I also don’t know POA. (Maybe power of attorney, but doesn’t make sense).

    “Recision of security interest” sounds a lot like a document that attempts to void out the part of the loan papers that let the lender repossess the car on default.

    CFO is chief financial officer, an executive at the lender organization.

    UCC is the Uniform Commercial Code, a set of laws enacted in most states covering business practice regarding contracts and such.

    SEC is the Securities and Exchange Commission, which regulates publicly traded stocks (“securities”). This seems to confuse the investment meaning of security with the different meaning of “security” on the loan.

    CFPB is the federal Consumer Financial Protection Bureau. This organization does do things to protect borrowers in default from unfair debt collection practices. I can’t imagine why they wouldn’t just leap into action for this case.

    Finally IRS collects federal income taxes. Form 3949a is a tattle tale form that lets you report things like your friend’s improper deductions to the IRS. That’s real nice.


  • Depending on which mission this is it could be a lot shorter. The original PLSS backpacks had a two hour air supply. The LM was powered by batteries and could only sustain life for 48-72 hours depending on configuration. If they launch and rendezvous with the orbiting CSM, they can extend their survival by several days, but there’s functionally nowhere to go.

    For my money the best way to go is probably in the suit, outside, and let the oxygen run out while the carbon dioxide scrubbers are still working.
