Born on 14 August 1933 in Winterthur, Switzerland, Richard Ernst is a Nobel Prize–winning physical chemist. Ernst attended ETH Zürich, where he earned his undergraduate degree in chemical engineering in 1956 and PhD in physical chemistry in 1962. His doctoral thesis centered on the newly developi...

The award rejection that shook astronomy

Happy 100th birthday Margaret Burbidge! The British astronomer has analyzed galaxies and quasars, explained how stars produce chemical elements, and developed instruments for the Hubble Space Telescope. Her 1957 paper with Geoffrey Burbidge, William Fowler, and Fred Hoyle (B2FH) explai...

Charm-quark decays violate charge–parity symmetry

For the first time, particle physicists have observed CP violation in particles containing charm quarks. Such observations are important because they yield clues toward answering a fundamental question: Why did matter win out over antimatter in the universe?

Born on 2 August 1902 in Cleveland, Ohio, Mina Rees was a renowned mathematician, educator, and science advocate. Rees grew up in New York City, where she studied mathematics at Hunter College, graduating in 1923. She went on to earn her master’s from Columbia University in 1925 and PhD ...

Fifth-generation broadband wireless threatens weather forecasting

The fight is on over 5G. Telecommunication companies and the US government promote the latest mobile broadband because it will provide faster data-transfer rates than the current broadband communication standard. But meteorologists, US science agencies, and other countries worry that strong 5G s...

Marie Tharp - Physics Today 2019-07-30 13:54

Born on this day in 1920 in Ypsilanti, Michigan, Marie Tharp was a geologist and oceanographic cartographer who helped create the first map of the ocean floor. Tharp determined that the ocean floor comprises mountains and canyons that rival those on the continents, and she discovered the mid-o...

An ultrafast eclipsing binary - Physics Today 2019-07-26 19:11

A newly discovered pair of white dwarfs share an orbit smaller than the planet Saturn. They whip around each other every seven minutes. Helpfully, the white dwarfs eclipse each other as viewed from Earth and thus enable determination of the mass and radii of each and the orbital decay due to the e...

Rosalind Franklin and the Double Helix - Physics Today 2019-07-25 14:48

Born on this day in 1920 in London, Rosalind Franklin was an x-ray crystallographer who made essential contributions toward determining the structure of DNA. Franklin received a PhD in physical chemistry from Cambridge in 1945. Her work in the early 1950s exposed elusive structural details about t...

Vera Cooper Rubin - Physics Today 2019-07-23 14:39

Born on this day in 1928 in Philadelphia, Vera Rubin was an astronomer who confirmed the existence of dark matter. Her measurements of galaxy rotation curves indicated the presence of additional, hidden matter that is now thought to account for nearly 90% of matter in the universe. Rubin was a...

Jika kita memandang ke atas langit, maka tak jarang kita melihat penampakan awan. Gumpalan awan berwarna putih adalah massa yang dapat dilihat dari tetesan air atau kristal beku tergantung di atmosfer di atas permukaan bumi. Bentuknya yang tak menentu menjadikan langit tampak indah jika dipandang dari bawah. Namun apa jadinya jika gumpalan awan membentuk serupa benda seperti tangan?. Tentu akan sangat menarik. Hal demikianlah yang terjadi pada gambar yang diambil oleh seorang wanita berikut ini. Dikutip Grid.ID dari The Sun, seorang fotografer amatir menangkap gambar formasi awan yang menakjubkan. Pasalnya, awan tersebut terlihat menyerupai sebuah tangan, yang kemudian dijuluki, 'Tangan Tuhan' oleh netizen. Fenomena unik ini bahkan diabadikan hanya dengan kamera ponsel pintar. Fotografer wanita bernama Louise Taylor itu menangkap gamabar luar biasa tersebut di daerah Highlands Skotlandia.
