The drone in the photo is an ST16B. It weighs only 142 grams, has no camera, costs less than 50 dollars and is designed for kids with no drone flying experience to learn the basics. It also provide…| carnotcycle
The computer spreadsheet evolved in the 1980s from paper-based bookkeeping and accounting worksheets and has since developed into a highly versatile tool, whether for complex business model canvase…| carnotcycle
For most people, sitting on an airplane is just like sitting on a bus or a train. The view from the window might be different, but the air you breathe is the same. Except it isn’t. Cabin air at altitude contains 25% less oxygen than it does at ground level. That’s a sizeable reduction that […]| carnotcycle
CarnotCycle is pleased to note that Leonid Alekseevich Molev, a 5th grade student at Lyceum No.8 in Voronezh in southwestern Russia, was awarded a diploma for his Computer Science research project …| carnotcycle
Every day this blog gets visits from all over the world, and in numbers which show that thermodynamics interests many, many people. They come from lands big and small, rich and poor, happy and less…| carnotcycle
OK so here’s a different way of illustrating the Calvin Cycle, the light-independent sequence of reactions in photosynthesis. There are no molecular representations, no long chemical names. Instead, this cycle shows the number of carbon atoms in the input, output and cycle intermediates, together with their average oxidation states and the number of molecules present. […]| carnotcycle
The Liberty Bell 3-reel slot machine, made by Charles August Fey, San Francisco, 1899 In the days of my youth, slot machines were part of the furniture of life. Essential scenery in bars, cafés, arcades, everywhere we chilled out. I have an analytical turn of mind but cannot recall ever applying it to these devices. […]| carnotcycle
I have seen the glow of a glowworm on only one occasion. It was many years ago in rural England and I remember wondering at the time whether the worm co-produced heat and light like an incandescent light bulb, and whether the fairly rapid sequence of switching the light off and on again was to […]| carnotcycle
It has been recently reported by international news agencies that tech giant Microsoft has signed a deal to purchase electricity from the currently shut-down nuclear plant at Three Mile Island in Pennsylvania in order to provide non-carbon energy to fuel the expansion of its power-hungry artificial intelligence (AI) data centers. The Three Mile Island plant […]| carnotcycle
The history of the incandescent electric light bulb goes way back to 1800, when Alessandro Volta invented an early form of battery called the Voltaic pile. This device produced continuous direct current, and it was soon discovered that when passed through conductive materials the current was capable of producing heat and, under certain circumstances, light.

Smarter than the average dice, don’t you think? Just an inch long yet weighing a nicely solid 14 grams, these 7-sided polished bronze stainless steel dice from The Trinket Emporium have a pleasant feel in the hand and roll amazingly well. And while rolling them, one can marvel at the engineering that makes a 7-sided […]| carnotcycle
