About This Design

Speed of Light Physics Tshirt

Speed of Light Physics Tshirt

The first true measurement of light-speed came in 1676 by a fellow named Olaf Roemer. He noted that the time elapsed between eclipses of Jupiter with its moons became shorter as the Earth moved closer to Jupiter and became longer as the Earth and Jupiter drew farther apart. This anomalous behaviour could be accounted for by a finite speed of light. He calculated that the speed of light was something like 2.14 x 10^8 metres per second. This measurement, considering its antiquity, method of measurement, and 17th century uncertainty in exactly how far Jupiter was from the Earth, is surprisingly close to the modern value of 2.99792458 x 10^8 metres per second. These modern values are obtained using devices called laser interferometers, which can very precicely pin down speeds and distances.

I give wanted to give this a 4 instead of a 5 because these Basic DARK T0shirts run unexpectedly SLIM or Narrow. Which is great if you do not have a potbelly, but I have a paunch. It isn't the shirt's fault that I've got a beer belly. The design and shirt itself is a quality cotton shirt. The color is more of a deep purple, but still a very pretty color. The Basic DARK T-shirts run a bit SLIMMER than the Basic Ts. The neck is a fraction narrower (or seems to be narrower) also. I'm a paunchy middle-aged woman and my neck is 12 inches (31cm) thick and the neckline fell about the same as in the photo of the man, and I had the desire to tug it a bit. So if you're a thick necked man or like loose shirts, be aware these are slimmer shirts. Once I get rid of my lockdown paunch it'll look great. The shirt washed well in cold water with no apparent bleeding. We don't have a dryer, so it hung dry. Did not shrink. Love the colors and the design. The design looks smaller on my shirt than it does on the model on-line. But still, it looks good on the shirt. The printing looks as it does on the model, just the size seems fractionally smaller. Washed garment in cold water, hung dry and design appeared unaffected.

I'm wearing this as I type... It's fab! Lovely quality. Soft material, perfect fit, nice and warm (It is very cold here, I live at the top of a hill and the wind is brutal in winter). Couldn't be happier with this. My Girlfriend really likes it as well - always a bonus! I was really impressed by how the printing turned out - my photo's don't do it justice. This is a complex design with a lot of colour variations but the finished article is really impressive. I couldn't be happier with how this has turned out. This is also one of my first designs to have been purchased by someone else (thank you so much!) I'm really curious to know what they think of the finished product...
