How to tell how tall a tree is
1) At a distance,bend and look back through your legs
2) Adjust distance until you can barely see the top
3) Height is your distance from the tree
⚠️ Assuming we look through our legs at 45° - accuracy might depend on the observer's flexibility!

A demonstration of the conservation of angular momentum using a Hoberman sphere. Angular momentum depends on the rotational velocity of an object, and on its rotational inertia. When an object changes its shape, its angular velocity will also change.

Much of the ham radio equipment on board the ISS dates back to Expedition 1. Help ARISS complete an upgrade of this equipment by making a donation today! #amsat #ariss #hamr fundrazr.com/arissnextgen?re…
A lot of things have changed in the nineteen years since the Expedition 1 crew arrived on the International @Space_Station, but many systems have been in operation for years. Do you know which of these technologies operates on orbit today? #TuesdayTrivia

Would anyone be interested in having this amp for their #QO100 station? I'm thinking about making a small batch of them. Let me know if you would like to have one too either by contacting me here or on arved@m6okf.co.uk.
