Twenty-seven people in Iran have died from drinking isopropyl alcohol in an attempt to protect from coronavirus.  It is true that washing the hands with soap or disinfecting with strong isopropyl alcohol, at least 70% concentration, or cleaning with 10% bleach solution will protect from coronavirus.  This does not mean that eating or drinking these substances will treat or prevent infection. 

Freeman Dyson, who has died at the age of 96, wouldn’t have liked being called doctor.  Many other sites will well cover his life and achievements.  He contributed to our understandings of mathematics and physics in a way very few ever have, ever can, or ever will.  He did so at a time of great tumult in the world.  He did contribute so much so quickly that he never got a PhD.  Certainly, he could’ve gotten a PhD.  However, he truly had philosophical differences with the system of getting a PhD.

Katherine Johnson, a Mathematician doing a job known as being a “computer” for NASA in the movie “Hidden Figures” died today at the age of 101.  She started out at a time where being such a human computer was looked about as lowly clerical work fit for women.  It was one of the few outlets for a woman of intelligence.  Computer programming and computer science for the up coming digital computers which she also worked on were looked at the same way.

Waves of geometry in four-dimensional space-time, that is what gravitational waves are.  The very definition of distance between points in space-time changes as these waves pass.   The objects in the space do not move but space itself changes momentarily.  The scale at which these changes can be measured right now are on the order of a few dozen widths of a proton.  Smaller than the average distance between the electron and proton in a hydrogen atom.   Yet, with laser light shining through interferometers, we can measure these changes.  From these we can learn about the fundamental nature of the universe.  Not by studying the matter and energy content of it but by studying the space that connects it

The number one pitfall of reporting on science is to take a single work, or single report and treat it as if it is proven as fact already.  In truth, real science knowledge is that which has stood the test of time.  That is not really exciting for reporting.  If a reporter wishes to discuss the latest developments, they must qualify it with the fact that it is a new study.  Even if it is peer reviewed, that is not even enough yet.   Until something is shown through consensus built by years if not decades of results to be either a “law” of nature or a “theory” of science, it should not be reported as fact.

A burst of gravitational waves followed closely by neutrinos and then the light.  While light's speed, in vacuum, is constant in all inertial reference frames, it does vary depending on the medium.  The same is not necessarily true of all waves which share this quality with light.  Neutrinos and gravitational waves would reach us well before the light did.   This is why the widely reported news of LIGO detecting a burst of gravitational waves is so intriguing to astrophysicists.   Here is what else the astrophysical community will be looking for and why.
