RGB Triad

That's how the three primary colors can be used to create a multicolor image.

Under the force of gravity, the raisin descends to the bottom. Then gas bubbles form on the rough surface of the raisin.

When there are enough bubbles, the expulsive force (Archimedes' principle) will cause the raisin to rise to the surface of the carbonated water. At the surface, the gas bubbles burst, and gravity causes the raisin to sink back down again.

Newton Disc

Allows to obtain white color from several rays of various colors.
The disk is divided into sectors of colors of the visible spectrum. When rotating it at high speed, you can observe how these colors merge to form a white tone.

Flash paper (nitrocellulose)

It has a characteristic combustion: no hint of smoldering, the jet of flame hits not only upwards, but also in all directions, indicating that in the "hearth of combustion" material burns without the participation of air oxygen. Finally, the fact that not only smoke, but also ash is not produced.

Using an acrylic prism and a gas pedal, we "catch" the electrons.

They easily penetrate deep into the acrylic and are quickly slowed down by colliding with the plastic molecules.

⚙️ Oldham clutch invented in 1821 by John Oldham 🤔

The cam-disc clutch or Oldham mechanism is a method of transmitting torque between 2 parallel but not coaxial shafts.

The mechanism consists of 3 discs, one connected to the input shaft, one connected to the output shaft, and the middle disc connected to the other 2 by a shoulder-to-hollow connection.

How LLMs Work — Explained Like You’re 10 (But Smarter) 🤓

Tokens – AI chops text into little pieces to understand it

Attention – It focuses only on the important words

Transformers – The brain design that powers the magic

Parameters – Billions of settings help it "remember" stuff

Training – First it reads the whole internet. Then it learns tasks

Prompts – Ask the right way, get a better answer

Context – It has a short memory, so keep it clear

Temperature – Low = serious, high = wild and creative

Embeddings – Turns words into numbers it can use

Few-shot/Zero-shot – It learns fast, sometimes with no examples

Chain-of-thought – Ask it to think step-by-step = smarter answers

Inference – You ask, it answers. That’s the payoff

Hallucination – Sometimes it just... makes stuff up

RLHF – Humans teach it what’s helpful or harmful

Alignment – We train it to follow human values
