Lise Meitner Is the Forgotten Female Physicist Who Deserved a Nobel Prize
Posted by Genevieve Klien in categories: military, particle physics
Nuclear fission — the physical process by which very large atoms like uranium split into pairs of smaller atoms — is what makes nuclear bombs and nuclear power plants possible. But for many years, physicists believed it energetically impossible for atoms as large as uranium (atomic mass = 235 or 238) to be split into two.
That all changed on Feb. 11, 1939, with a letter to the editor of Nature — a premier international scientific journal — that described exactly how such a thing could occur and even named it fission. In that letter, physicist Lise Meitner, with the assistance of her young nephew Otto Frisch, provided a physical explanation of how nuclear fission could happen.
It was a massive leap forward in nuclear physics, but today Lise Meitner remains obscure and largely forgotten. She was excluded from the victory celebration because she was a Jewish woman. Her story is a sad one.

The tallest building in California will be a 77-story ‘supertall’ skyscraper in Los Angeles
Posted by Genevieve Klien in categories: futurism, space
- Los Angeles could be getting a brand-new skyscraper that’s taller than the Wilshire Grand — the tallest tower in California.
- The planned skyscraper is 77 stories high and features a mixture of condos, hotel rooms, and commercial space.
- The future development represents a growing trend of supertall construction as cities compete to have the most impressive skylines.
Los Angeles has endured endless criticism for its low-lying slab buildings, flat-topped towers, and mismatched design aesthetics.
In 2013, the former architecture critic at Los Angeles magazine, Greg Goldin, lamented the city’s “dull” and “mediocre” landscape.

NASA Will Flight Test a Nuclear Rocket by 2024 and Other High Tech NASA Projects
Posted by Klaus Baldauf in categories: robotics/AI, space travel
A portion of NASA’s $21.5 billion 2019 budget is for developing advanced space power and propulsion technology. NASA will spend $176 to $217 million on maturing new technology. There are projects that NASA has already been working on and others that NASA will start and try to complete. There will be propulsion, robotics, materials and other capabilities. Space technology received $926.9 million in NASA’s 2019 budget.
NASA’s space technology projects look interesting but ten times more resources devoted to advancing technological capability if the NASA budget and priorities were changed.

Check Out This Incredible X-Ray ‘Superbubble’ That’s Nearly 5,000 Light-Years Wide
Posted by Genevieve Klien in categories: cosmology, nuclear energy
This incredible image shows a pair of “nuclear superbubbles,” one over 4,900 light-years across and the other over 3,500 light-years. They’re emanating from the center of the galaxy NGC 3079, likely the result of a central black hole consuming matter and spewing it back out.
Or, the superbubbles could be from a starburst, a faster-than-usual stellar birth. The bubble-like shape could come from shock waves and compression within the cooler gas. But there’s still an element of mystery here, as the smaller bubble seems to be emanating synchrotron emission, or high-energy x-rays from spiraling electrons, while the larger bubble isn’t.
