So what is a #Supermoon? Well, the Moon is typically ~ΒΌ million miles away (30 Earths in a row), but thanks to its elliptical orbit, that distance changes. Tonight the Full Moon is 2-Earths closer than normal (221,823 miles away), making it appear ~15% brighter than usual hence #Supermoon! πŸ”­πŸ§ͺ

A screenshotted part of an article that reads: When 2 Chainz, a rapper, asked to sample β€œThe Old Dope Peddler” in one of his tracks, Mr Lehrer was keen to help. β€œI grant you motherfuckers permission to do this,” he supposedly answered. β€œPlease give my regards to Mr Chainz, or may I call him 2?”

Two images sit side by side: one shows a TV screen with the word β€œNetflix” on it with a male viewer in the foreground and a brick wall in the background, while the other shows an advancing Asian elephant with vegetation in the background. Each has the caption: β€œbig, long memory, knows when you’re watching”.

Big congratulations to Chunk for taking the crown as this year's #FatBearWeek winner! Today feels like as good a day as any to tell you all about a little trick that bears have to ensure pregnancy takes place during OPTIMAL FATNESS.

Not just a pretty face: lab-grown diamonds in engineering Diamond is an incredibly versatile material that can help us solve some of our biggest problems – from diagnosing diseases earlier to making the electronics underpinning data centres more efficient. L...

I fell hard for diamonds reporting this feature for #Ingenia – did you know they could play a role in destroying forever chemicals, diagnosing infectious diseases, and making our data centres less energy-hungry?

Playmobil figure kitted out as prehistoric iceman Γ–tzi.

#OTD 19 September 1991, walkers in the high Γ–tztal alps on the Italian border, found a body melting out of the ice. It turned out to be the remains of a c.5200 year old man preserved with all his kit.
Of course, it was essential to replicate him in Playmobil.

A crudely assembled image of an old motor car, which looks like little more than two bicycles with a seat in the middle, upon a background of a rolling German countryside with different trees. In the foreground is an autobahn sign along with another sign that reads β€œNope no autobahn yet. Come back in 40+ years. Danke.”

#Onthisday in 1888, Bertha Benz took the first ever long-distance car journey.

She solved snags as they arose, using a hat pin to clear a blockage, and replacing the brake blocks with leather, effectively inventing brake pads.

Plot that shows a one-in-X chance of an event occuring to someone or the planet over a human lifetime on x-axis and then the one in X chance of a fatality if that event occurs. Several events are plotted such as contracting rabies, influenze, being hit by a car, being attacked by a coyote or elephant, being struck by lighting, carbon monoxide poisinging and the Earth being struck by an impactor greater than 140m in diameter

Hahaha! This preprint! πŸ”­πŸ§ͺ

Chance of event happening to you or the planet, and if so, chance it will be lethal?

Turns out .... we are more likely to be hit by an impactor 140m and greater than:

- being struck by lightning
- getting killed by elephants and coyotes
