Fleming's Vacuum Tube Rectifier Navy Blue T-Shirt
Vacuum tube, diode - an invention of sir John Ambrose Fleming.
Fleming undertook research of the thermionic emission effects discovered and patented in 1883 by Edison - the current flow between electric lamp's filament and external electrode. He discovered that the flow is possible only when the electrode has positive potential with respect to the filament. Based on this discovery he developed the first two-electrode vacuum tube - a diode. The tube was an "instrument for converting alternating electric currents into continuous currents". Fleming proved its usefulness as a radio wave detector which was what he was working at, at the time, at Marconi's company.
The T-shirt is a part of the Breakthrough invention collection created to commemorate key discoveries of science and technology. It presents a drawing from the original patent application.

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.
