New paper in Communication Physics: A phase diagram for bacterial swarming

April 6, 2020

I’m happy to say that the paper “A phase diagram for bacterial swarming” has been published in Communication Physics (https://www.nature.com/articles/s42005-020-0327-1). This paper is the result of ancient long-running research (started in 2015…) and is joint work with Avraham Be’er, Bella Ilkanaiv, Daniel Kearns, Sebastian Heidenreich, Markus Bär and Gil Ariel. In it, we analyze how … More New paper in Communication Physics: A phase diagram for bacterial swarming

A primitive model for genetic recombination

August 17, 2015

Introduction: I’m taking a class in general genetics at the Technion, and there we learned about genetic recombination, and in particular, homologous chromosome crossover: a phenomenon where chromosomes exchange sections between themselves during meiosis. When this happens, some of the members of the population exhibit “recombinant genomes”, which are different than their parent genomes should … More A primitive model for genetic recombination

Book review: The Andromeda Strain

July 9, 2015

*** spoiler included *** Do you know that feeling where you say to yourself “I’ll just check out this article on wikipedia” and then five hours later when you finally raise your head from the screen and gasp for air after having dredged half the the internet you cannot help but wonder “where the hell … More Book review: The Andromeda Strain

A short note about amino acids and Hamming distance

October 26, 2013

It’s always interesting to see how work in one area of mathematics seems to help or imply results in a totally different field. Not long ago, I read a bit on the problem of random packing – if you park cars randomly on a street, how many cars can you fit in before you run … More A short note about amino acids and Hamming distance

An Interesting Hitchhiker

April 22, 2012

Most people hardly take the time to stop and take a good look at the world. We have our lives to run, people to meet, places to go, things to do, and that’s a fact. What’s more, we already know quite a lot about the basic things we deal with in our everyday lives. We … More An Interesting Hitchhiker

Wheat Fields and Emergence

March 29, 2012

My daily cycling takes me through wheat fields, ponds, and pastures, and I take great delight riding through nature. At first I was not familiar with the terrain at all, and I had to carefully inspect where the grass was high, where there were logs blocking my way, and which canals were easiest to go … More Wheat Fields and Emergence

Growing Trees in Your Computer

November 26, 2011

Plants and flowers are beautiful. That’s the main reason we keep them around our houses. Supposedly, if you want to have any chance with girls, at one time or another you’re going to have to give them flowers of some kind (although I personally prefer to give potatoes). Greenery is life. A house full of … More Growing Trees in Your Computer

Two Bachs at a Time

November 5, 2011

I happen to have a radio receiver both in the living room and in my own room. Often both of these are turned on at the same time to the same station (the countrywide classical station, obviously), so they play exactly the same thing. I noticed a peculiar effect when the two radios were turned … More Two Bachs at a Time

Infrared Sensing and Human Imperfection

April 30, 2011

Can humans see in the infrared? By definition, no, but as we will soon see, the definition of “infrared” might be different for different people. When we see objects, what we actually see are photons that are reflected or created at their surface. We call these photons light. Our eyes are only sensitive to some … More Infrared Sensing and Human Imperfection

Of Mark and of Biology

November 14, 2009

As some of you might know, I wanted to take biology during high school, but instead chose physics, for various reasons. However, this does not mean that my interest in biology lessened, and I still find the topic quite fascinating, especially when related to microbiology or physics. During the weekend, I have written two short … More Of Mark and of Biology
