The world we live in is incredibly information-rich. The reality we think we live in turns out to be a tiny proxy of the real thing. Useful and often beautiful, but a proxy constructed in our brain from slow moving signals from our sensory organs. Today I received an email... Continue reading

What is a ruby and why is it red? Why is the friction so low on a sled? On a plot of P versus T, plot out the the phases of helium-three.... A favorite professor loved to craft simply stated preliminary exam questions that happened rhyme. Parts were often difficult... Continue reading

Some years ago I found myself at West Point talking about the sort of things a pacifist and a group of Colonels and Generals might find interesting. It was near the holiday break and staff members had brought in a huge feast. I mentioned to a Colonel that it struck... Continue reading

A few years ago my refrigerator crashed. Some poorly written code put it in an unfortunate condition that forced a failure and the loss of quite a bit of food, and days without refrigeration. . The product was out of warranty by a few months and I had to cough... Continue reading

There is a serious need for an inexpensive centrifuge that doesn't use electricity in the developing world. People have tried salad spinners, but they're way too slow - about 6oo rpm. Other solutions involve car or motorcycle parts and run on battery power, but performance is low and cost is... Continue reading

To start off the New Year a reason to be thankful... When I was in high school I came across one of those factoids that both amazed and bothered me. One of those things that forces you to dive in deeper so you can sleep. It turns out the neutron... Continue reading

My dear friend Norm Schryer died unexpectedly this morning. This past week hasn't been a kind one. Norm was one of those special beings you sometimes hear about and, if you're really lucky, you get to work and play with them. He was a Bell Laboratories mathematician - he'd probably...

A ninth grader asked me what e was all about. She had seen it looking through her brother's calculus book. I took out my iPhone and opened a calculator (rpn of course;-) and rambled on more or less like this... Imagine you're going to deposit a dollar in an extremely... Continue reading

Entering the exam room you're asked if you're carrying anything metal one last time even as you walk through a metal detector. You lie down on the exam table and try to find a comfortable position as the QALO ring wearing technician checks the machine's status and inserts your IV.... Continue reading

come on let's go and play.... Well .. maybe a snowflake or two rather than a snowman. Years ago C.L. Strong's Amateur Scientist column in Scientific American talked about homemade ice crystals. Homemade apparatus for carefully controlling temperature and humidity so you could study their growth. These pieces were great... Continue reading

At it's core particle physics is very simple. You smash to tiny particles into each other hard enough that something dramatic happens and then sift through the debris. The first major experiment I worked on was a clean example. A beam made of a tiny negatively charged particles - pi... Continue reading

I pulled a large knife switch on the wall and heard some relays close as the bank of lights came on for the first time in months. It was my third visit, but the place seemed strange and out of place. The underground concrete lined cavern forty by two hundred... Continue reading

Last night I found myself reading a paper on a futuristic propulsion system. It's been around for several years and manages to excite the tech beat websites every time. I'll spare you details, but it makes a rather dramatic claim. Extraordinary claims require extraordinary evidence. This wasn't it. It was... Continue reading

In October of 1958 Oliver Smoot became a measurement's namesake and part of MIT lore. As part of his fraternity pledge task his body was to be used to measure the Harvard Bridge - a span connecting Cambridge and MIT with Boston proper. At five foot seven Smoot was the... Continue reading

The latest iPhone’s ability to simulate bokeh - a lovely effect you can get with larger cameras and careful attention to settings - has people excited about smartphones replacing DSLRs … While that may be the effect, something much larger is going on. What excites me most about photography is... Continue reading

Let's say you find a determined bug - a bug with the singular ambition of walking in one direction. It covers no more and no less than one centimeter every second. You also have an unusual band a meter in circumference. You make a mark on it and start the... Continue reading

I've never taken a programming class, but have done a fair amount over the years in a variety of languages. I'm not fond of it myself - at least not something I'd like to do for a living. You get spoiled being around the likes of Brian, Ken, Bjarne and... Continue reading

On September 17th Canadian engineer Todd Reichert squeezed into the cockpit while his crew installed the aerodynamic shell around him. A rather tight fit, it does allow for the centimeter or two height variation a human body can experience during the day. He switched on the GPS, pedal ergs and... Continue reading

Tell me a bit about your favorite trips? Forty minutes into the interview and Bill hadn't asked anything about my specific work. We touched tracker action pipe organs, color vision, and several topics I can't remember. Here was a famous Bell Labs director asking about trips. Road trips.. I like... Continue reading

This past Monday Randall Munroe posted a beautifully done timeline of the Earth's average temperature since the last glaciation on xkcd. It's beautifully crafted, but... scroll down and enjoy and I'll pick up on the other side.. I first became aware of global warming in the mid 80s. Back then... Continue reading

It turns out The Simpsons has little math and science jokes making their way into the show - usually as very short sequences that fans can stop and study. In a favorite episode Homer scribbles on the blackboard leaving four items.1 398712 + 436512 - 447212 immediately caught my eye... Continue reading

1900 at the Olympics in Paris François Brandt and Roelof Klein had qualified in the coxed pairs, but had lost a race to a French pair. Thinking it over with an unspecified amount of alcohol they came to the conclusion they couldn't change their rowing performance, but perhaps Hermanus Brockmann... Continue reading

I while back I asked if there was interest in a few Olympic themed posts - after all, sport is a gateway to many other areas. Charlie replied: How about the high jump? I was fascinated by Randall Cunningham's 18 year old daughter's comment on getting her head over the... Continue reading

Recently I sent out a note that was well received by several people, so I reproduce it here: There are a few friends I take long wandering conversations through a city with. Great conversation is always wonderful, but I tend to get distracted. A few years ago I a conversation... Continue reading

We have our fundamental needs. I want to shiver with awe and wonder at the Universe. Last week I was walking in a relatively dark area around home and found myself looking towards Sagittarius - one of the most beautiful regions of the night sky. On clear dark nights the... Continue reading
