The visit to CERN

Over the half term I ran a school trip to CERN in Geneva. I’ve run the trip many many times now. This time, however, I ran the trip whilst suffering from bronchitis! With fistfuls of cough sweets and antiinflammatories, I got through it. While I was there, I decided to do a few live streams.ContinueContinue reading “The visit to CERN”

Today’s the end of the half term, so I need a break. I won’t be blogging every day, but I’ll try to post some stuff during my school trip to CERN.

They also state that a lack of sleep increases the risk of illness after exposure to viruses. How much of an increased risk is it? According to Cohen et al (2010), the riskContinueContinue reading “Why sleep matters”

Being kind on the internet

Little did I expect but YouTube’s algorithm picked them up and thousands of people watched them. Consequently, dozens of people decided to comment on them. That’s fine, of course, but many of the comments were actuallyContinueContinue reading “Being kind on the internet”
