In Russian culture “British Scientists” is a running joke and Internet meme used as an ironic reference to absurd news reports about scientific discoveries, particularly ones that have no practical value. For example, “British scientists debunked the myth that mice love cheese.”

Kay Antonelli‘s official civil service title, as printed on her employment documentation, was “computer”. During her work as a computer, she invented the subroutine (a sequence of computer instructions which can be used repeatedly). Today, the subroutine is essential programming for all.

Astronomers who work on the Sloan Digital Sky Survey have released a brand-new 3D map of the entire universe.
The Sloan Digital Sky Survey is a decades-long project that has only had one goal: to map the universe. Now, it seems that they’ve managed to produce the largest-ever map to date.
Over 100 scientists have been working on the project, and the mapped over two million galaxies and quasars while doing so.
The scientists placed the Earth at the center of the map.
We are located at the center of this map. As we look out in distance, we look back in time.
When looking at this map, we see the light that is arriving on Earth from other galaxies. That light takes a long time to reach our planet. For example, it takes 2.5 million years from light from the Andromeda Galaxy to reach us here on our planet.
The map also shows other galaxies that are different distances from our home planet.
The scientists also explain that they use a “cosmic distance ladder” to figure out how far away a galaxy is.
This method depends on making accurate measurements of distances to nearby galaxies and then moving to galaxies farther and farther away, using their stars as milepost markers.
Astronomers use these values, along with other measurements of the galaxies’ light that reddens as it passes through a stretching universe, to calculate how fast the cosmos expands with time, a value known as the Hubble constant.
All of this going over your head a bit? Yeah, us too.
So here’s a video to explain more…
Isn’t this information amazing? Don’t forget to share the map with your friends, and let us know what you think about it in the comments!

A unit of ‘shyness’ called a dirac is named after the famous theoretical physicist and father of quantum physics, Paul Dirac. Known for his succinctness, his colleagues jokingly defined 1 dirac as 1 word per hour.

In 1918, microbiologist Alice Catherine Evans warned that raw milk should be pasteurized to protect people from various diseases. She was met with skepticism, particularly because she was a woman and did not have a Ph.D. During the 1920s, scientists around the world made the same findings.

In 1749 a scientist, Emilie du Châtelet, feared that bearing a child at 42 would be the last thing she did. She worked furiously on a magnum opus that would eventually change the world of physics. Within days of completing her work, she gave birth to a daughter and died soon after.

For months, scientists in France could not figure out why seagulls they were tracking were traveling far inland, away from their breeding colony. Eventually, they traced the seagulls’ path and discovered they were visiting a chip factory.
The term “scientist” was coined in the 1830s to describe Mary Somerville. A woman. Because the usual term “man of science” didn’t apply and she wasn’t just a physicist, geologist, or chemist – she was all three.
Scientist Henry Cavendish suffered from extreme shyness “bordering on disease”. He discovered several laws not attributed to him because of this shyness. Had secret staircases in his home to avoid his housekeeper -females caused him “extreme distress” and devised a note system to talk to her.
