The unit circle is where trigonometry starts to make sense.
Every angle gives a point, and that point gives us cos θ and sin θ. Once students see this visually, trig feels less like memorising formulas and more like reading coordinates.

How AI really works.

This tiny operation, repeated across millions of neurons, powers ChatGPT, Grok, image models, and everything in between.

The limit as h → 0... Watch the secant line collapse into the exact tangent at that point.

This is the single most beautiful moment in all of calculus. The definition of the derivative, live.

This periodic table is sized by how abundant each element is on Earth.

Look how tiny Helium (He) is... yet we fill party balloons with it like it’s unlimited.
Helium is irreplaceable for MRIs, superconductors, aerospace, and cryogenics… and once it escapes into space, it’s gone forever. We should treat it as the precious resource it is.

[Wevolver @WevolverApp]

From connected sensors and AI to drones and smart machinery, the latest agricultural revolution is transforming how we grow food, making farming more efficient, sustainable, and data‑driven than ever before. IoT technologies help farmers monitor soil, crops, livestock, and equipment in real time, boost yields, reduce waste, and tackle climate uncertainty.

With global food demand rising and billions still facing hunger, these innovations could be key to feeding the world smarter and greener.
