THE LEGO KIT. “All visible matter in the Universe is made of fundamental building blocks, the elementary particles. The group of particles known as fermions consists of two types: quarks, which make up protons and neutrons; and leptons, namely, the electron, muon, tau particle and neutrino.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

“The Sombrero Galaxy as never seen before? Discovered by Pierre Méchain at the end of the 18th century, it is one of the sharpest and most spectacular images captured by the Hubble Space Telescope, especially because the angle at which it is seen from our planet creates a tremendously impressive visual effect.

INTUITIVE BIAS. “One reason we consider Newton brilliant is that in order to come up with his second law he had to ignore some data. He had to imagine, for example, that things were falling in a vacuum, free of the interfering effects of air resistance.” https://www.theguardian.com/technology/2022/jan/09/are-we-witnessing-the-dawn-of-post-theory-science?CMP=Share_iOSApp_Other View in LinkedIn

SURPRISE. “In a mirror world, antiparticles should behave in the same way as particles. But it emerges that leptons — neutrinos, electrons and their more exotic cousins — might not obey this expected pattern.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

HIGH ENERGY RAYS. “The longstanding simple picture of a featureless and universal power-law energy spectrum of CRs might have been finally overcome. A remarkable change of spectral indices has been established for several CR energy spectra at a kinetic energy of about 300 GeV.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

PROMISING DATA. “CR protons and nuclei. Accurate, recent measurements of the most abundant CR species, such as protons and helium have recently revealed new and unexpected features in their energy spectra, that may shed new light on the acceleration and propagation mechanisms of CRs in the Galaxy.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

TANTALIZING CLUE. “It is now generally accepted that the positron and electron spectra can be jointly understood only assuming the existence of as yet unknown sources of high-energy positrons and electrons in the Galaxy. The positron excess has caused a huge interest.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the moiré interference caused by stacks of imperfect graphene and their tremendous applications. Carbon is now threatening to augment or displace silicone electronics. It is no accident that the strange properties of this atom resulted in carbon-based life. View in LinkedIn

MATTER>ANTIMATTER. “This imbalance, at a level of a few particles per 10 billion photons, is ultimately responsible for the existence of Earth, planets, stars and ourselves: if there were equal amounts of matter and antimatter, they would have destroyed each other in the early Universe and annihilated into photons. No matter would have remained.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
