n 1911, Norwegian explorer Roald Amundsen reached the South Pole, followed by Scott who died on the return journey. Shackleton searched in his mind for some other daring goal. He finally settled on crossing of the Antarctic continent from coast to coast via the South Pole, a distance of about 1800 miles.
“A Boy and His Atom” is a 2012 stop-motion animated short film released on YouTube by IBM Research. The movie tells the story of a boy and a wayward atom who meet and become friends. It depicts a boy playing with an atom that takes various forms.
Sometimes, there’s this “Eureka!” moment — that one in a billion — that sweeps us off our feet and transforms society. Just think of the transistor, the internal combustion engine, the atom, the theory of evolution, even the freakin’ wheel. It’s difficult to imagine the world today sans these amazing discoveries and great works of science. There’s so much we take for granted today, so from time to time it’s nice to sit back and take a crash course in history. Don’t worry, I’m not here to bore you with too many words. Instead, we’ll dive deep into some of the . Instead, we’ll dive deep into some of the most interesting moments in the history of science, human ingenuity and nature.
It all starts with a lucky spermatozoon and one egg. When the two merge, a genetically unique entity is formed shortly thereafter, called a zygote which has half of its DNA from the sperm, and the other half from the egg. The zygote first divides into two identical cells, called blastomeres. Five days after conception, the grouping of cells are now called a blastocyst. A cavity appears in its center. It has an inner group of cells which will become the embryo and later the fetus, and still later the newborn. In between, there’s a lot of things happening and this fantastic animated infographic designed by Eleanor Lutz does a great job summing things up visually.
Approximately 3.8tn cubic metres of water is used by humans annually with 70% being consumed by the global agriculture sector, according to a report issued by the Institution of Mechanical Engineers (IME). Strikingly, up to 50% of all food is thrown away before it gets the chance to reach consumers, often out of frivolous reasons. In terms of water that’s 550bn cubic metres that go to waste each year. At the same time, approximately 795 million people in the world are chronically malnourished and 1 in 10 lack access to clean water. While policy makers should take more notice and take measures to curb waste, there’s much you can do yourself to cut on waste. Eglė Plytnikaitė, an illustrator from Vilnius, Lithuania made some insightful drawings showing how much water goes into some of the most popular foodstuff.
Here, we see a skull magnet interact with a mass of ferrofluid. A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluid was invented in 1963 by NASA’s Steve Papell as a potential liquid rocket fuel. Basically, they are colloidal liquids made of nanoscale ferromagnetic particles suspended in a carrier fluid (usually an organic solvent or
A 300 meter long (984 ft) glass suspension bridge, 180 meters (591 ft) above the ground has recently opened in Hunan, part of China’s Shiniuzhai National Geological Park. As if that wasn’t scary enough, the entire thing is made of glass-like material, and it’s transparent. Eloquently named Haohan Qiao or ‘Brave Men’s Bridge’, the bridge is an adventure in itself, as the
Some parts of Mexico are plagued by a severe drought, threatening food security and local agriculture. But the same drought created a surprising, ghostly appearance: a 16th century church emerging from the middle of a reservoir. The Nezahualcoyotl reservoir, located in southern Mexico, has dropped over 25 meters (80 feet) due to this year’s drought. As the water levels dropped
Every year Nikon holds the Small World Photomicrography Competition awarding the very finest photographers that capture the essence of the micro world. For 2015, the winner was Ralph Grimm from Australia with a close-up of a bee eye covered in dandelion pollen grains. This was no lucky shot. Grimm says it took four hours to prepare, including setting focus increments, proper illumination and stacking.
Previously stored away in government archives, some 170,000 photographs from the time of the Great Depression have been now released to the public by Yale University.
