Enlightenment when? - Mind Matters

Michael Corballis Mar 22, 2020

I recently encountered the following prescription from a Faculty of Education at a leading New Zealand University. At first I wondered if it was another product of the postmodern generator (http://www.elsewhere.org/journal/pomo/), designed to create gibberish in the postmodern form, but I’m told it is real: The “schooled” society: Towards the close of the 1980s, both anti-racist and anti-sexist initiatives in … Read More

Eight new COVID-19 cases today. It’s no surprise when you look at some numbers - Physics Stop

Marcus Wilson Mar 18, 2020

So, as I sit at home with a very, very slight headache (i.e. not at work when I would otherwise be so), the now familiar figure of Ashley Bloomfield reports eight new confirmed cases of COVID-19  including two in Waikato. A surprise, given that we had just twelve yesterday? No. A worry? Maybe, but no more so than it … Read More

A beginning of semester corona-rant - Physics Stop

Marcus Wilson Mar 04, 2020

I’ve had enough of COVID-19 now. No, I haven’t had it (well, not that I’m aware of), what I mean is I’ve had enough of reading misleading headlines, hearing xenophobic attitudes and dealing with outright selfish behaviour. Let me elaborate: Point 1 We know that every outbreak will be accompanied by a kind of tsunami of information, but also within … Read More

First recorded ‘marsquakes’ reveal the red planet’s rumbling guts - Guest Work

Guest Author Feb 25, 2020

Katarina Miljkovic We’ve all heard of earthquakes, but what about marsquakes? NASA’s InSight mission has, for the first time, recorded seismic activity coming from Mars’ interior. The observations, recorded in 2019 and published today, will help understand the red planet’s internal structure, composition and dynamics. It opens a new chapter in planetary geophysics and exploration. The NASA InSight … Read More

When is the day inserted into a leap year? - Out of Space

Duncan Steel Feb 24, 2020

Surprisingly enough, one could argue (as I often do) that the day inserted into a leap year is not that we label 29th February, but actually the 24th of February. Here I explain why, briefly.  Almost everyone assumes that the day added into February in a leap year is the 29th, but that assumption is based on a lack of … Read More

New launch of 60 SpaceX satellites crossing NZ - Out of Space

Duncan Steel Feb 22, 2020

Last Monday SpaceX launched another clutch of Starlink satellites into low-Earth orbit, bringing up to 300 the number of these units intended to bring 5G internet to the whole globe. In this post I present a movie showing how all 300 such satellites will be zipping around our planet over the next eight days (until the end of the month), … Read More

Mucky rain - Physics Stop

Marcus Wilson Feb 20, 2020

While the south of New Zealand has been struggling with too much rain in recent days, here in the north we are so very short of it (though Saturday’s forecast looks promising).  Basically, we have had almost none since Christmas. As someone who relies on rain to wash the car, this means my car is now looking rather mucky. Read More

New disease and virus have now officially been named On the 11th February, the WHO Director General announced a new name for the disease: COVID-19 which is short for coronavirus disease 2019.

The numbers are the numbers, except when they’re not. - Physics Stop

Marcus Wilson Feb 14, 2020

I’m not quite sure of what to make of the new figures for COVID-19 (as we must now call the novel coronavirus – though I’m not sure the capitalisation is correct) from Hubei province: Image from https://www.bbc.com/news/world-51495484  The spike yesterday is a consequence of a using a different way of defining a case – one based on a clinical diagnosis (i.e. Read More

Update on how to see the Space-X satellite chains from NZ - Out of Space

Duncan Steel Feb 08, 2020

In a previous post I described briefly when and how the Starlink satellite chains – recent launches by Space-X in a scheme to bring 5G internet connectivity to the whole globe – could be seen from New Zealand with the naked eye. Here I provide an update and predictions for the next several days.  My preceding post included … Read More
