#PDF #paper by Sturman and Wright on “the #history of #Tellurometer”, a surveying instrument that could measure distances to 1ppm with microwaves. The figures are missing from this version. “The Tellurometer is basically a time measuring device and this is achieved by measuring the phase of a frequency which has been modulated onto the carrier.”
#ebook of Rolt’s #metrology book Gauges and Fine Measurements, recommended by Gelbart, with tables where people measured the sizes of pieces of metal over 100 years.

another #metrology #paper #PDF about the #Tellurometer, explaining how it works using signals of 10 MHz, 9.99MHz, 9.9MHz, and 9MHz, modulated onto a 3GHz carrier wave. It explains the whole algorithm.

#clickbait #video listing the top 10 least attractive hobbies men can have according to women (for #dating, I suppose, but the source of the poll is unclear): 1. The Manosphere. 2. Gambling. 3. Porn. 4. Arguing online. 5. Funko. 6. Marijuana. 7. Clubbing. 8. Cigars. 9. Crypto. 10. Makeup. And the most attractive: 1. Reading. 2. Foreign languages. 3. Playing instruments. 4. Cooking. 5. Woodworking. Oh, this is from the Date Psychology blog. They didn’t really add any content in the parts of the video I actually saw, just a bunch of talking-head filler.
#video of testing similar consumer products from 01975 and 02025, more or less, such as drill bits, tape measures, ratchets, Old Spice, and Coca-Cola, Hanes T-shirts, Gillette razors, etc. Generally the new products are higher in quality than similarly-priced old products, but most of the old brands have become much cheaper and also lower in quality.
#Funcrunch about what it means to them to be agender and transmasculine: “In my case, it means that I cannot define what it means to be a man, woman, or any other gender with referring to body parts, and body parts do not define a person. (...) Despite being agender, I am not anti-gender. I was more that way when I first transitioned, because I thought that since the concept of gender made no rational sense to me, no one could actually have one.” #trans #LGBT
