Hello again Science Fans!

Did you notice a change today? Me either, but at 5:44 AM today, astronomical Autumn began in the Northern Hemisphere, the Autumnal Equinox. So happy fall.

Our calendar has gotten much more active now that schools are back in session and more seminars are on the schedules. We’re listing 94 events over the next two weeks. More will be added to our calendar as we find them, and some already listed will be updated as titles, abstracts, and speakers are provided. As always, should you want to attend an event we list, click through to the host’s website for any last minute updates or cancellations. Or

Let’s start out with something fun, and not truly science-related. It may make you laugh, may make you mad, may make you shrug your shoulders and go “so w

These past few years have put us all through a bit of a wringer. Prior to the pandemic, 11% of Americans reported symptoms of anxiety and depression, according to the Household Pulse Survey, a tool of the Census Bureau. Then came COVID, and that number increased to 42.6%. Today, it is down to 20.7%, but that is still almost double pre-pandemic numbers. The political climate certainly contributes to this, I’m sure. But the biggest component seems to be young adults. According to “The Morning” newsletter from the New York Times on August 8, the percentage of young adults reporting symptoms had been rising for around a decade before COVID. Uncertainty about their future, inflatio

Hello again science fans!

This is the first SciSchmooze of the astronomical summer, what with the solstice having occurred this past Thursday. Different countries refer to the start of summer at different times, some May 1, Some June 1. In the US, we tend to say it starts on Memorial Day. The astronomical start is celebrated by some as Midsummer’s Day.

Last Wednesday was Juneteenth. What seems like a recent holiday has roots going back to 1865. Heather Cox Richardson explains the history, as well as efforts since then to get around the freedom Juneteenth represents.

I want to follow up on two stories I’ve writen about in the past.

Hello again Science Fans! It is a 3-day holiday weekend for most of us, so enjoy the unofficial beginning of summer. The astronomical start of summer, the summer solstice, occurs on Thursday, June 20 this year. If you want to know more about the solstice, check out this article from the Farmers’ Almanac.

If you are one of those people who, like me, is interested in how things work, you may enjoy this video. It is about Olympic Curling Stones, how they are made, and why they cost so much. The process is fascinating. The granite only comes from one place on earth, Ailsa Craig off the Scotish coast. Two types of granite are used in each stone.

Curling can only be described as an odd sport. It is sort of like shuffleb

Hello again Science Fans! I’m filling in for David this week (and next). For those of you who celebrate, Happy Easter!

More about Time

In my February 25 SciSchmooze, I went into a discussion about time. There was one error (that I know of) in that discussion where I said how there was a two week difference between the start of Daylight Savings Time here in the US versus Europe, with them making the change later than us. The difference is actually three weeks, with Europe changing to Daylight time early this morning. They will return to st

Hello again Science Fans!

This year is a leap year, when one day is added to the calendar to account for the difference between the tropical year and the common year. The tropical year is the time it takes Earth to make one complete orbit around the Sun, or 365 days, 5 hours, 48 minutes, and 45 seconds. It would be pretty difficult to have a calendar that matched that exactly, so we use the common year length of 365 days. That means we fall slightly behind the actual year by almost 1/4 day. So every 4 years (with exceptions) we add one day to the calendar, that being February 29, to get back in synch, more or less.

Back in the day, namely 46 BC, the Julian cal
