1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
Apple announces Siri, a digital personal assistant. In addition to being able to recognize speech, Siri is able to understand the meaning of what it is told and take appropriate action. [12] 2014: April 2: Application: Microsoft announces Cortana, a digital personal assistant similar to Siri. [13] 2014: November 6: Invention
2019 – Advanced LIGO and VIRGO detect GW190814, the collision of a 26-solar-mass black hole and a 2.6-solar-mass object, either an extremely heavy neutron star or a very light black hole. [292] [293] This is the largest mass gap seen in a gravitational-wave source to-date.
Siri (/ ˈ s ɪər i / ⓘ SEER-ee, backronym: Speech Interpretation and Recognition Interface) is a digital assistant purchased, developed, and popularized by Apple Inc., which is included in the iOS, iPadOS, watchOS, macOS, tvOS, audioOS, and visionOS operating systems.
Apple's Siri (2011), Google's Google Now (2012) and Microsoft's Cortana (2014) are smartphone apps that use natural language to answer questions, make recommendations and perform actions. 2012 AlexNet , a deep learning model developed by Alex Krizhevsky , wins the ImageNet Large Scale Visual Recognition Challenge with half as many errors as the ...
The revamped Siri assistant instantly reminds Ramsey of the man's name, which is impressive, but the feature won't be available on iPhone 15s or iPhone 16s until 2025 or later.
The black hole aspect of the Schwarzschild solution was very controversial, and Einstein did not believe that singularities could be real. However, in 1957 (two years after Einstein's death), Martin Kruskal published a proof that black holes are called for by the Schwarzschild solution.
The crucial phase of our discovery of black holes took place in a suitably dark period of human history – World War II.
