Georgia O'Keeffe holds the record for the highest price paid for a painting by a woman. On November 20, 2014 at Sotheby's, the Crystal Bridges Museum of American Art bought her 1932 painting Jimson Weed/White Flower No. 1 for US$44.4 million (equivalent to US$57.2 million in 2023). [ 14][ 15] Among the listed top 89, only six are paintings by ...
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology. In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the cosmic microwave background (CMB) , estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna .
Wisconsin was decided by just 20,000 votes in 2020, remains deeply divided politically and is expected once again to be one of the most important states in this fall’s presidential matchup ...

Using the values known in 2018 and Planck units for Ω Λ = 0.6889 ± 0.0056 and the Hubble constant H 0 = 67.66 ± 0.42 (km/s)/Mpc = (2.192 7664 ± 0.0136) × 10 −18 s −1, Λ has the value of = = = where is the Planck length. A positive vacuum energy density resulting from a cosmological constant implies a negative pressure, and vice versa.
The Greisen–Zatsepin–Kuzmin limit ( GZK limit or GZK cutoff) is a theoretical upper limit on the energy of cosmic ray protons traveling from other galaxies through the intergalactic medium to our galaxy. The limit is 5 × 1019 eV (50 EeV), or about 8 joules (the energy of a proton travelling at ≈ 99.999 999 999 999 999 999 98 % the speed ...
