Hungarian invention - the ballpoint pen

“Today we celebrate Bíró and his relentless, forward-thinking spirit on the 117th anniversary of his birth”, says US-based search giant Google in today’s edition of its popular Google Doodle series. Did you know that the ball-point pen, commonly known as a “biro”, was invented by a Hungarian-Jewish journalist László Bíró?
He was born on 29th 1899 in Budapest. Writing a lot with the fountain pens of the time, but in the vicinity of newspaper presses, he noted that the thick, sticky newspaper ink dried far more quickly than the runny India ink used in fountain pens, which required blotting, drying and lots of patience to prevent smudges. He came up with the idea of using it in an internal cartridge that would not need refilling. Working together with his brother, György, a chemist, László developed a new type of pen made up of a ball that turned in a socket. As the ball turned, it picked up ink from a cartridge and rolled to deposit it on paper, much like a newsprint roller transfers an inked image to paper. Bíró presented the first prototype of the ballpoint pen at the Budapest International Fair in 1931, later patenting his invention in 1938.

IM SO ANGRY 

so i was like driving home and was in the left lane, there’s a merge lane to my left and this fuckign guy speeds up to get in front of me and we’re side by side and he’s going OFF AND YELLING AND PUTTING HIS FINGER UP AT ME LIKE CUNT YOURE THE ONE ABOUT TO RUN INTO ME YOU WERE FUCKIN BEHIND ME AND YOU PURPOSEFULLY SPED UP ND NOW YOURE MAD AND THEN HE TOOK A PIC ON HIS PHONE OF MY LICENSE PLATE!!!! (WHILE STILL DRIVING WHICH IS FUCKING ILLEGAL!!!) 

im so mad i need to have a valium or something and tHEN this stupid ass woman parked halfway across the only free spot at the chemist

in conclusion = I HATE SA WHY CANT ANY OF YOU CUNTS DRIVE

I think that everyone should take a look at these gorgeous drawings representing Women and their accomplishements in Science, by Rachel Ignotofksy - a fantastic illustrator and graphic designer. She also has a lil Etsy shop where she sells her prints here!!!

Felt alone day and night lost many relatives and friends not to mean we dont like those but , We purely love our subjects little more than all…

lets celebrate every day and never give up !!!!!!!!!

Cheap and abundant chemical outperforms precious metals as a catalyst

A team of Caltech chemists has discovered a method for producing a group of silicon-containing organic chemicals without relying on expensive precious metal catalysts. Instead, the new technique uses as a catalyst a cheap, abundant chemical that is commonly found in chemistry labs around the world—potassium tert-butoxide—to help create a host of products ranging from new medicines to advanced materials. And it turns out that the potassium salt is more effective than state-of-the-art precious metal complexes at running very challenging chemical reactions.

“We have shown for the first time that you can efficiently make carbon-silicon bonds with a safe and inexpensive catalyst based on potassium rather than ultrarare precious metals like platinum, palladium, and iridium,” says Anton Toutov, a graduate student working in the laboratory of Bob Grubbs, Caltech’s Victor and Elizabeth Atkins Professor of Chemistry. “We’re very excited because this new method is not only ‘greener’ and more efficient, but it is also thousands of times less expensive than what’s currently out there for making useful chemical building blocks. This is a technology that the chemical industry could readily adopt.”

Physics envy.

In science, the term physics envy is used to criticize a tendency (perceived or real) of softer sciences and liberal arts to try to obtain mathematical expressions of their fundamental concepts, as an attempt to move them closer to harder sciences, particularly physics.

A physicist’s response.

“To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature … If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.”
