I remember seeing the Amiga bouncing ball demo and being amazed. https://www.youtube.com/watch?v=-ga41edXw3A The Amiga was the second computer that I ever owned. The first was a C6…

Certainly most universities now have a very strong liberal bias. I think most science departments were left leaning in the 1950s, but it is stronger now. (I think colleges and univ…

I'm retired. I hope to get a 3% per year income from my savings every year after inflation and taxes. If my state implemented a 1% wealth tax on savings each year, I would go bankr…

I also "had an Iron Man moment last week" as a mathematician. I've been doing joint math research with two friends (professors) on a project for several years. Last week, I decided…

ikrima, Do you have any links to your research or paper titles?

How about: (* Mathematica Notation, Assume x>0 ) If[ x order x^2 error ) If[ x> 10^10, Sqrt[x], ( order 1/Sqrt[x] error ) ( else ) Sqrt[x +1] ] ] ( I guess the If statements take t…

Us humans do have difficulty with safety. Sometimes we are able to overcome that problem to an extent. Here are some the few examples where humans have done well with safety: FAA c…

I think that finding proofs for open mathematical questions should count as critical thought. (See https://medium.com/%40cognidownunder/three-erdős-problems-fe... )

AI makes it possible for someone who has never written code to generate a program that does what they want. One of my friends wanted to simulate a 7,9 against a dealer 10 upcard in…

This morning a person posted a question to the Reddit group r/Mathematica ( https://www.reddit.com/r/Mathematica/comments/1s1fin2/can_ho... ). I asked GPT to write code to address …

Type "Polar plot 6 curves of the form r = (1 + Sin[2^(k - 1) t]/2^(k - 1)) where k =1, 2, .., 6 and t=0 to 2 Pi each curve should be a different color" into ChatGPT5. https://chatg…

I think this 6 set Venn Diagram is nice because I made it. :) http://162.243.213.31/wp-content/uploads/2012/08/Ven3.png

> I became a mathematician. From this childhood exposure, entropy was the first mathematical "concept" beyond arithmetic that I understood. Very cool.

So, I think that I can avoid a lot of the data leak problems. There might be a simple way to do this with a crypto-currency. If possession of a credit card is considered proof of a…

Even after reading the article, I think there are reasonable ways to set up a low cost system that uses zero-knowledge proofs to "prove" your age without disclosing your identity. …

My son accidentally brought a knife to school at age 12 -- maybe a 4 inch blade. When he realized that he had a knife in his backpack, he told his teacher. He was suspended from sc…

When I was in eighth grade my advanced algebra teacher said "I wonder if you always did your homework in pen, would you make fewer mistakes." That was 45 years ago. Now I am a math…

This might be the best article that I have read this year. It might change the way that I program. I really want to write up examples for each of the ideas presented: Monotonicity,…

Forth :) It's been like 30 years since I the last time I wrote a Forth program that was more than 10 lines long---fond memories.

I believer there is an error in "Readers comprehend “the boy hit the ball” quicker than “the ball was hit by the boy.” Both sentences mean the same, but it’s easier to imagine the …

I also wrote a brute force, kinda dumb, depth-first Suduoku solver. I think it took me a few hours in C or C++. At every node in the search tree, I just checked to make sure no con…

The article is a very enjoyable history of how Cuneiform was deciphered by a small group of often competing scholars.

Oh yes, I also will listen to NPR and other radio news when I'm driving.

I forgot. I also watch NBC Nightly News and "What about it?" on YouTube.

Mostly I read Slashdot, HN, and the Wall Street Journal. I read the Economist when I feel like paying for it (sometimes I get a deal like $50 for the digital version for a year). I…
