Seven Years of India GDP Growth Was Overstated at 7% Per Year Instead of 4.5%

Official Indian estimates placed annual average GDP growth between 2011-12 and 2016-17 at about 7 percent but new research estimates that actual growth may have been about 4.5 percent with a 95 percent confidence interval of 3.5 – 5.5 percent. The evidence, based on disaggregated data from India and cross-sectional/panel regressions, is robust. India’s former …

SpaceX Raptor Engine 600 Hz Vibration Problem Fixed so Hopper Ready To Hover

Exciting progress in Boca! Hopper almost ready to hover. Based on tonight’s test, looks like 600 Hz Raptor vibration problem is fixed. pic.twitter.com/9bLWOHG0sV — Elon Musk (@elonmusk) July 7, 2019 Great video. Couple notes: Raptor designed for subcooled CH4/O2, so propellant density & thrust increase up to ~8%, as needed for mission. 380 Isp & …

Quantum Control in Nanodiamonds

Quantum coherence control usually requires low temperature environments. Even for nitrogen-vacancy center spins in diamond, a remarkable exception, the coherence signal is limited to about 700 K due to the quench of the spin-dependent fluorescence at a higher temperature. Here researchers overcome this limit and demonstrate quantum coherence control of the electron spins of nitrogen-vacancy …

Magnetoresistance in a magnetic nodal semimetal

Transport coefficients of correlated electron systems are often useful for mapping hidden phases with distinct symmetries. Researchers report a transport signature of spontaneous symmetry breaking in the magnetic Weyl semimetal CeAlGe system in the form of singular angular magnetoresistance (SAMR). This angular response exceeding 1000% radian−1 is confined along the high symmetry axes with a …
