If, like I am, you’re tired of people getting ensnared by the nonsense in the “What the Bleep…” movie, and asking you to explain it….(I scared myself just now by looking at the technorati tags for What the Bleep and Bleep…yikes)… please please help out Jennifer Saylor, a blogger who … Click to continue reading this post
So you’ll recall that when we thought we had twelve planets we started trying to think of new mnemonics to help people remember the planets’ ordering. For example, from Yvette: My Very Educated Mother Can’t Justify Someone Using New Planetary Conventions… oh no, they haven’t named the last one yet!!! … Click to continue reading this post
Ok… Let’s try this again shall we? It’s official! There are eight planets in our solar system. The vote has taken place. Last week’s proposals have been rejected. Pluto has been demoted, apparently. They were voting on the following (I got this here): 1) A planet1 is a celestial body … Click to continue reading this post
The saga continues. Nobody yet knows how many planets we have. There has been fierce argument at the International Astronomical Union. As a result, the definitions of last week have been revised. “Pluton” has been discarded as a term (partly because of the clash with a geological term, a clash … Click to continue reading this post
Apparently the hole in the ozone layer above Antartica is stabilizing. Some of you will remember the late 80s, when the hole was discussed a lot in the popular press. It was a huge problem. The hole we made meant that we were losing our protection from the sun’s ultraviolet … Click to continue reading this post
Some days I’m optimistic, and I think we’ll change our behaviour in time. We’ll be able to stop destroying our environment quite so recklessly. We’ll stop our dependence on oil and other fossil fuels. We’ll stop fighting ridiculous wars over such fuels…. etc. Other days, stuff like this happens, and … Click to continue reading this post
Well, the press conference I told you about has happened! This is so exciting! There’s new and very direct proof from observations of the Bullet Cluster with the Chandra X-ray Observatory that Dark Matter really exists. So the need to make modifications to how gravity works on large scales in … Click to continue reading this post
Aaron Bergman has written an extensive review of Peter Woit’s attack-book on string theory. I’ll let you read the thoughtfully written 11-page pdf document linked there. I think that Aaron deserves some sort of medal or other award for making the effort. Peter responded here. Note from the title that … Click to continue reading this post
Below (nearer the end of this post) is the description of the “Uncertainty” event (Thursday 31st August, 7:00pm, USC’s Annenberg auditorium; much more here) part of USC’s Visions and Voices program I told you about in the previous post. These are, as I said, events that build upon the Categorically … Click to continue reading this post
This year, there’s going to be even more to do on the USC campus to broaden your mind, and several events which link USC with off campus venues such as theatres, museums, and performing arts centers. The (then) new Provost, Max Nikias, announced his “Arts and Humanities Initiative” in his … Click to continue reading this post
“Yeah, this string theory stuff is nice and all, but what does it have to do with the price of eggs?”, is not one of the questions I’ve had to field at the end of a public lecture, but it could have been. If it had come up, I could … Click to continue reading this post
Well, I gave the talk and I’m back at my temporary apartment. I’m exhausted, as is always the case for me after general talks. Does that happen to you? I think I managed to get across everything I wanted to (see the previous post) and it was a nice complement … Click to continue reading this post
[Update1…. Oh no it’s not official! See here.] [Update2: The vote is in… see here.] [Update3: (7th June 2010) Moved the updates 1 and 2 one sentence earlier since, bizarrely, some readers (ahem! you know who you are…) don’t seem to read further than one sentence, or check the posting … Click to continue reading this post
NASA is about to make an exciting announcement, apparently. On Monday 21st August there will be a press conference, and there will be actual information (they say) at several places mentioned in this link. I have not the slightest idea of the details of the announcement [but see update below], … Click to continue reading this post
Well, I had the “Aspen Physics Preview” interview for the station called “Grassroots TV” this afternoon. It was a pleasant chat with host Sy Coleman about aspects of research into fundamental physics and string theory. I don’t have a good sense of what it was like since I was focusing … Click to continue reading this post
