Although the presence of ET planetary-based life as we know life and don’t know it, is all, comparatively as, and less and in gradations more technologically and cognitively achieved or advanced than our species, such life, in mathematical and thermochemical terms, is a must on a vast in raw numbers but quite possibly…

This post is adapted from this research paper that you can read/cite for more info. It analyzes and visualizes 100 cities around the world.
This blog is not peer reviewed at all. I write it, I put it out there, and people read it or not. It is my little megaphone that I alone control.
I was reading the latest issue of the journal Science , and a paper mentioned the compound Cr 2 Gr 2 Te 6 . For a moment, I thought my knowl...
Eva Silverstein has a new preprint out, entitled The Dangerous Irrelevance of String Theory. The title is I guess intended to be playful, not referring to its accurate description of the current st…
Update: An updated version of this blogpost was published as a (peer-reviewed) Letter to the Editor at Bioinformatics, sans the “sociology” commentary. I just came back from CASP13, the…
Okay I ended up making this write-up waaaaaay too long, so before I get into any of the jargon, let’s take a look at the finished product:
If you like this, you might also like my Instagram channel Nerd on Bars @nerdonbars where I calculate the power output of various athletes and myself.
How early, sustained, supermassive black hole jets carved out cosmic voids, shaped filaments, and generated magnetic fields
Evidence that discoveries are getting smaller on average
By good luck we have been able to make an emergency landing on this uninhabited space station. There have been no casualties. We all count ourselves fortunate to have found safe haven at a moment when the expedition was clearly set on disaster.
However, no experiment with actual coin-tosses has been done to investigate whether the predicted effect is empirically observed. Diaconis et al noted, correctly, that to estimate the probability with a S.E. of 0.1% would require 250,000 tosses, but this seems unnecessarily precise. Let's work with numbers of tosses…
How I used AI to investigate millions of historical records and surfaced a forgotten meteorite report, three lost rhinos, and unrecorded volcano eruptions.
For the purposes of this article, when I talk about "dreams" and "dreaming", without any further qualification, I am referring to the dreams that occur during sleep.
Update: This post was an Editor’s pick by Cristy Gelling at Science Seeker, and was included in Bora Zivkovic’s top 10 science blog posts of the week. Lately, I’ve got colors on t…
How Stephen Wolfram helped with the theory of interstellar travel, communication with aliens and questions from the actors in “Arrival”, the movie.
There is a grand tradition of scientifically minded science fiction authors creating not just the characters in their novels but also the brass tacks scientific details of the planets they reside on. This is the art and science of Worldbuilding .
When listening to music, however, we are not just listening to a series of disconnected instants. Instead, the way things sound depends on the notes we have heard. In other words, we integrate over time . One of the most important functions of a musical scale is to limit the overall pitch content of what we're hearing…
So this is a bit of a deviation from my normal MATLAB oriented posts. In-fact MATLAB was not used once in this analysis! I've been followi...
I dig into the research on intrinsic motivation. Super interesting subject. Long but hopefully quite thorough.
In recent months there has been a proliferation of AI-generated proofs of various old and new results, some of which have been formalized in the proof assistant language Lean. However, checking tha…
For the longest time I had seen this framed image entitled “The First TV Image of Mars” in an out of the way place at JPL. I loved taking people there showing them this low res image and how it had been made by coloring numbers that were stapled to a wall. When I got to curate an exhibition about data and art, I had…
Every now and then the orbital motion of a body doesn’t match our prediction. And that might lead to interesting discoveries.
Recently I stumbled upon an interesting paper for implementing motion sensing requiring no special hardware, only a speaker and mic ! Unfortunately the paper didn't include code to test it, so I decided to reproduce it here on the web!
About six years ago on this blog, I started thinking about trying to make a web-based game based around high-school algebra, and ended up using Scratch to write a short but playable puzzle game in …
SpaceX priced its debut at a $1.77 trillion valuation, edging Saudi Aramco's $1.7T for the largest in history. Each block is $25 billion. Aramco was the only company that ever came close; the famous tech IPOs barely register.
