Can zapping your neck help you quickly learn a foreign language?

Someday it may be possible for a soldier to stick a tiny electrode behind her ear in order to learn a foreign language more quickly. (via STAT)

Can zapping your neck help you quickly learn a foreign language?
A new project at DARPA aims to improve people’s ability to learn new things by stimulating nerves in the neck or behind the ear.

'Kindles now', Programming as a Way of Thinking, 3 New Eye-Catching Bridges Rise in New York


"The ability to execute code makes programming a tool for thinking and exploring. When we express ideas as programs, we make them testable; when we debug programs, we are also debugging our brains."

Programming as a Way of Thinking
The power of modern programming languages is that they are expressive, readable, concise, precise, and executable

鈣鈦礦是指一類陶瓷氧化物，其分子通式為ABO3；此類氧化物最早被發現者，是存在於鈣鈦礦石中的鈦酸鈣(CaTiO3)化合物，因此而得名。由於此類化合物結構上有許多特性，在凝聚體物理學方面應用及研究甚廣，所以物理學家與化學家常以其分子公式中各化合物的比例(1:1:3)來簡稱之，因此又名「113結構」。

巴斯德滅菌法1862



【那一年的這一天】
如果沒有法國人巴斯德的話，可以確定的是，世界人口絕對不會像現在這樣爆炸，因為人類健康仍然在很大程度上，受到看不見的「微生物帝國」的威脅和宰制。巴斯德的研究直搗「微生物帝國」，甚至提出「預防接種」的劃時代理論，還進一步發明狂犬病、炭疽病疫苗，破了微生物的功。這人根本是微生物的剋星來的，因此被稱為「微生物學之父」。

巴斯德還發明一種低溫殺菌的「巴斯德滅菌法」，廣泛用於牛奶、葡萄酒、啤酒和果汁消毒。如果沒有巴斯德，這些生鮮飲料不可能發展出龐大的產業，甚至不可能擺上大賣場的貨架，只能走「觀光果園」的路線，現擠現喝。


巴斯德還創辦「巴斯德研究院」，延續他「對抗微生物之戰」的戰果。1983年巴斯德研究院第一個成功分離出人類免疫不全病毒（HIV），對於白喉、破傷風、結核、小兒麻痺、流行性感冒、黃熱病和鼠疫等也有許多革命性的發現。1908年起，該機構已有8位科學家獲得諾貝爾獎。


【民報】【那一年的這一天】1862.4.20 巴斯德滅菌法首次測試完成
舉世聞名、被廣泛運用在延長牛奶、酒類等食品保存期限的「巴斯德滅菌法」（pasteurization），首度於1862年4月20日這天，由法國科學家、「微生物…

The Brain Science of Conformity

Why are we so quick to follow along when people around us embrace a falsehood? Because of the anxiety, unease and disgust caused by standing apart.

The Brain Science of Conformity
It’s a problem in schoolyards, board rooms and, especially lately, in politics, where social media has proven a powerful tool for rallying people to untruths.

Why Are Some Mice (and People) Monogamous? A Study Points to Genes

Why Are Some Mice (and People) Monogamous? A Study Points to Genes

By CARL ZIMMER

A groundbreaking study has found that genetic variations in mice are linked to parental care and monogamy, the first time such a link has been found in mammals.

Lidar - Wikipedia

https://en.wikipedia.org/wiki/Lidar

Lidar (also called LIDAR, LiDAR, and LADAR) is a surveying method that measures distance to a target by illuminating that target with a pulsed laser light, and measuring the reflected pulses with a sensor.
