Nowadays it has become exceedingly hard to distinguish legitimate academic endeavours from scam in my mailbox. Not even AI filters can sort stuff out properly: my inbox often contains invitations to fake conferences, or to publish with non-existing journals, while my spam folder at times contains honest invitations>
I was reached this evening by the news of the passing of a dear friend, Enrico Stomeo. Enrico was an architect by profession, but for me he was rather defined by his activity as an amateur astronomer - in fact, if I had to define what a serious amateur astronomer is, I would more or less consciously be describing>
Aircraft engines are more efficient at higher temperatures, but this requires thermal treatment of engine components at very specific high temperatures in excess of 1300 °C. If the heat treatment temperature deviates too much from the optimal temperature, the treatment may be inadequate.

Optics normally treats the behaviour of packages of light waves (photons). However, when passing through appropriately shaped fields, particles may behave similar as photons. A beam of electrons that is not too dense will under such conditions behave similar to light beams that pass comparable lenses. In a dense beam>
