Here's how it all started

If anybody is reading this decades after I post it, indeed if even the capability is still available to access an internet, then this, in a nut shell, is how it all started.


AS OF TODAY
The United States of America is a failed experiment.
We went out in the way a bad joke would have predicted. We lost against our own racism and sexism, our endemic illnesses whose symptoms were intensified by corrupt law enforcement and institutionally rotten mass media. Undone at the final hour by a bizarre codicil in a slaveowners’ constitution. Undone, pushed over the edge—but the edge was too close all along. When it really mattered, we proved ourselves incompetent: not able to handle our civil responsibilities, indeed, in a sense, not ready for adulthood. In the name of national glory, we have voted ourselves a government of the worst. And now a generation will grow up ignorant, poor and sick, if they get the chance to grow up at all. Many of the things we will lose will be things we can never regain, from international respect to endangered species to the lives of our loved ones.
Many good people will keep up the good fight and stir up, as John Lewis says, the good trouble.
The abyss has opened before us.

Whether the future we make for ourselves will have anything to commend it now depends upon our ability to stare into that abyss and make it blink.

In the Beginning...

What was going on at the beginning of time? The beginning of the universe? Can we even know what  that situation might have been? As physics finds reductionist answers to the questions of how the universe works, this is the last great unanswered question.

Sean Carroll has a presentation addressing this issue.

Mathematica and automobile reliability

I'm an unabashed enthusiast of Mathematica. And here's an example of a down-to-earth use.

The elusive black hole event horizon

As is noted in this link, a black hole event horizon while believed to be a canonical part of the whole back hole scenario, direct evidence is hard to come by and the concept still in doubt. Researchers mentioned in the link have been able to observe a putative black hole and measure the glow of the matter falling into the black hole. Basically if there is an event horizon then the glow should be somewhat less intense than if the material is simply splashing onto a black hole's surface. Conclusion:  event horizon. The take-away data graph is here:

Would it be possible to develop a Moore Method for teaching high school students mathematics?

Proposal: Would it be possible to develop a Moore Method for teaching high school students mathematics?

review moore method

find way to adapt to high school

contrast with existing programs

Comment 1.
The “Trki-Wiki” is now a group effort. Timothy Gowers, at Cambridge, started it as a collection of ‘tricks’ to solving math problems at all levels in 2009. Since it was a Wiki others could also add to it or edit it. In 2012 due to illness Gowers announced he might have to abandon the effort. Others felt it was so valuable ownership was distributed amongst other mathematicians.

Comment 2.
Russian Mathematics! I love the concept. From what little experience I have, all second hand, it seems even online participation is successful.

Comment 3.
Hung-Hsi Wu. Professor at Cal Berkeley who has devoted his life to the methodology of teaching grade school mathematics. He has numerous very approachable published articles at the link

Comment 4.
Gelfand was another Russian emigre to the U.S. A
professional mathematician who as a hobby started a correspondence school for teaching secondary school math. He wrote a series of beautiful little books for each subject. He's since passed away and the university that was supporting the project disbanded it. You can still buy his books, used, on Amazon. I have a set that I treasure. They are uniquely suited for isolated self-study as that was the concept of correspondence classes.

Comment 5.
Mathematics is comprehensible: After what ever road you take everybody still ends up at the same understanding. There isn’t English math, or American math, or black math (actually been proposed), or math for girls, poets, business, liberal arts, etc, etc. It’s all just math. Period.

Comment 6.
Richard Feynman studied calculus from a popular little book first published in 1910: “Calculus Made Easy,” by Silvanus Thompson which was re-issued and slightly updated by the famous Martin Gardner in 1998. The book starts with an “Ancient Simian Proverb:"
“--What one fool can do another can.”

Comment 7.

Don’t give up!!!

Einstein Archives, Digitized Papers

A short post of immense significance. Caltech has provided a link to the digitized collected papers of Albert Einstein. Now one can just find everything the MAN wrote in original German and English translation. No longer any need to save pennies to buy a hardbound version, although who wouldn't want a collection of his 1905 year's papers?
