MrReid.org launched on 30th August 2007. Last year I published a Five Year Review, and I thought I’d follow that up this year with a review of 2012-2013.

September

My two favourite posts from September had a common theme: refractive index. Demonstrating Refractive Index, a video of a neat refractive index magic trick, made it to the top of reddit’s r/science subreddit, and My Favourite Photograph from the Olympics continued the refractive index theme, looking at a neat demonstration of total internal reflection.

October

Surviving Acceleration is a neat post that I’ve referred to on many occasions in my teaching, especially when trying to explain the usefulness of logarithmic graphs, and I’ve also gone back to Tog a number of times, especially when looking at the mathematics of thermal energy transfer and Newton’s Law of Cooling.

How are Mushroom Clouds Formed? answered a question I’d always wondered about, and is something that I point people towards when they (understandably) assume that mushroom clouds and nuclear weapons are intrinsically linked.

November

An excellent podcast inspired Solved Games, and a couple of interesting papers from the arXiv inspired Earthquake Cloak, a post about shielding buildings from earthquakes. I wrote about Blood Types because I was teaching the topic at the time.

December

December saw a rare non-science related post as I got obsessed with publishing for BERG’s Little Printer and I finally got around to finding out why resistors have strange values. I also wrote about mach cones and fission-fragment rockets.

January

In January I looked at Gravel Gerties, which are used for the manufacture and maintenance of nuclear weapons, and Whipple Shielding, which is used to protect spacecraft. I also wrote about a very old-fashioned pregnancy test and looked at GPS in Space.

February

There were no really outstanding posts in February, but I love the visuals of Rifling and have surprised a lot of people with the Energy Density of Coal.

March

I love Radomes, so it was inevitable I’d write about them at some point and I was also very interested by the Mean Centre of World Lighting. I found the topic of Depth Perception in Jumping Spiders very interesting, but I’m not sure I explained it particularly well.

April

April was a busy month, with a trio of posts about nuclear weapons: The Trestle, the Composition of Nuclear EMPs, and Critical Mass and Fizzles. I was also very pleased with a post about Google’s “Leap Smear“.

There was also a dumb April Fools post.

May

In May I finally worked out what the problem with Disk Drive Sizes is, and looked at the mysterious FOGBANK, as well as touching upon the risk of asteroid collisions and how satellites are pointed.

June

A post about Automatically Removing Objects from Photographs continues to get a lot of attention and I was also pleased with On the Emission of Light and Laser Gyroscopes.

July

July was a bit of an odd one, with a bunch of unconnected posts like Fish Ladders, the colour you see with your eyes closed and the Galileo Thermometer.

August

In August I finally worked out how cooling towers work and what Lagrange Points are, as well as writing a very popular post about bullshit marketing equations.

So here’s to 2013-14. I hope you’ll keep reading.
