Today, I learned about:

We have come to the end of yet another interesting month. Below are some interesting things that caught my interest:

On 5G, Covid-19, cocksureness and today’s challenges

My alma mater, Chalmers University of Technology in Göteborg (Gothenburg), Sweden was founded on 1829-11–05. And each year since 1991, around this day, there is a lecture about popular science, the William Chalmers lecture, held by a prominent researcher. This year, it was Erik Ström, professor at the Department of Electrical Engineering.

Erik leads a team which has participated in developing the modern day communication technologies, all up to 5G. And now it is planning the development of the successor, 6G. Erik talked about that, but also about the omnipresent Covid-19 and how one can estimate the probability of having the virus if the test result is positive, etc. All this was done in a very leisurely style, I am sure you will enjoy it as much as I did!

See references #1 and 2 below for all details.

One instant from Erik Ström’s speech held on 2020-11-05

What does bimonthly mean?

If you learn that a certain measure should be taken bimonthly, what does that mean? Should it be twice a month or every other month?

The answer is that it could be either way! You have to find out by the context, if you can.

See also reference # 3 below.

What is round and attracts the automated video recording system?

As we all know, technology of all sorts are so developed nowadays that many things can handed over to automated systems and they take care of them brilliantly. But there may be glitches…

The Scottish football club Inverness Caledonian Thistle FC employed an automated video recording system to transmit their games online to their fans who were locked down at home. The system was programmed to keep track of the ball. It worked fine until a certain day the system confused the ball in the field with one of the linesmen.

See for yourself in reference #4 below.

That’s what I learned in school today!


1: About the lecturer and the main content of his speech

3: The ambiguity of ‘biweekly’ and ‘bimonthly’
