ShopInBerkeley undergoing major remodel

I’ve been running ShopInBerkeley.com since 2001, and it’s time for a face lift. I’m converting it to a WordPress run site, although getting all my pages over to WP will take several months. The new format should be easier to navigate, and be easier for me to update. It will also have the ability for visitors to make comments on the individual business pages.

Mt. Diablo beacon to be lit in commemoration of Pearl Harbor attack

This Sunday, December 7th, the beacon atop Mt. Diablo will be lit at dusk in commemoration of the attack on Pearl Harbor on December 7th, 1941. After the attack, blackouts in the Bay Area caused the beacon to be turned off, and after the war it was not turned back on.

“Since 1964, the Diablo Valley Pearl Harbor Survivors Association has lit the old aircraft beacon atop Mt. Diablo every Dec. 7 in remembrance of those lost on that “day of infamy” and throughout World War II. Sunday at dusk, look to Mt. Diablo for the beacon that was turned off on Dec. 7, 1941, and not relit until the first memorial ceremony at the top of Mt. Diablo in 1964.” From http://www.insidebayarea.com/trivalleyherald/localnews/ci_11102595

Great physics cartoon

Egg drop contest

One of the classic physics projects is an egg drop contest. Students develop an apparatus to hold an egg that will be dropped from the second or third floor (depending on how high the teacher can get easily). This cartoon is a great twist on that, and maybe a reason to use only unfertilized eggs…

How to fix pixelated images in IE

I don’t use Internet Explorer (IE) much (Firefox is better in so many ways), but since I write web pages I have to check how they look in IE every so often. I found that most of the images in IE were pixelated (jagged edges where lines should be clear), so I finally went off to hunt for a solution. I found one here:

Ryan McFarland at ziek.com

If you are experiencing pixelated images in IE, take a moment to visit Ryan’s web site and he walks you through all the steps, including screen shots so you can be sure you’re doing it correctly. I tried just the second fix (using Regedit), and that solved the problem without changing my screen font size (the first fix does this, and may make your screen font too small to comfortably read).

PS. I haven’t used Windows Vista, and these instructions are for Windows XP. Not sure if you’ll have the problem with IE in Vista, nor if these instructions will work in Vista.

Tips for using the TI 83/84 calculator in a science class

I’ve posted my student handout “Analyzing data using your TI-83 or TI-84 calculator” to the web. You can find it and more TI tools at trampleasure.net/science/TI-calculators/

I presented this handout at the Northern California/Nevada American Association of Phyiscs Teachers November 8 meeting at Foothill College.

Jesse Arreguin for Berkeley City Council, District 4

Well, it’s “almost” November of an even year, which means it’s time for Berkeley City Council elections. I’m endorsing Jesse Arreguin, and helping his campaign by weaving his web site, jessearreguin.com.

If you live in District 4 (Dona Spring’s district), I hope you will support and vote for Jesse. If you have any questions, please email me or visit his web site (the web site is still in the infancy state, but should be much fuller by the end of the weekend).

Peets or Starbucks? An organic coffee review

Yesterday I stopped by my local Peets (Walnut and Vine, the original) to see if they had organic decaf beans (about 7:00 pm, very slow inside). The bean counter worker looked at the selection and said “No, not certified, but they’re all basically organic except for the certification.”

I said thanks and left the store, but a few doors away I was upset enough about his response that I decided to go back. I asked him what he had meant by “basically organic.” He said that they don’t really use any pesticides, that Peets is careful who they buy coffee from, and implied that therefore they used no/fewer pesticides. I asked if he could show me this in writing, and he went in the back to see. When he came out, he said they had nothing. I asked if the manager was in, and he went and got someone.

The shift leader (”I’m not the manager”) repeated his claim that all the beans are grown with “almost no pesticides.” I again asked if they had this in writing. She said no, but that was what they were told in trainings. (Peets website “Lean: How Coffee is Grown” make no mention of pesticides or organic farming practices.) I left with three of the workers there wishing me a good evening in tones that didn’t seem to convey any real sense of sincerity.

After this experience, I thought I’d see what response I got at the Starbucks down the street (Cedar and Shattuck, “Mortuary Mall” for those who’ve been in town a while). I asked if they had any organic decaf. The woman at the counter told me that no, while they had organic beans that were decaf, the decaffeinating process made them not organic. I said that the “Swiss water process” didn’t make it not organic, and she replied that Starbucks doesn’t use the water process, and she wasn’t sure why. We had a good, short discussion about how at least the beans were being grown in an organic matter, so it was better for the farms and farmworkers, even though at the last minute some chemicals got added to it.

I must say that I was pleased about the honesty I got from the worker at Starbucks. She said that she had convinced many people to get the chemically treated, formerly organic decaf beans, but was very clear on what made them non-organic.

By the way, both companies sell organic regular coffee, just not organic decaf.

So, bad marks for both companies for not carrying organic decaf. Peets gets serious bad marks for not even admitting that their coffee isn’t organic unless they can say so in writing, essentially trying to sell me that there’s no real difference except for the label, what I would consider deceitful marketing–and this all the way up to the top person in the store. Good marks to Starbucks for honesty and knowing what actually happens to their beans, and not trying to sell some that weren’t grown organically as “almost organic.”

Carbon sequestering in the seabed, nice video too

Science Friday, my favorite radio show when I’m not teaching on Fridays, had a great piece today on carbon sequestering on the ocean floor.

What if you could take CO2, pump it down a deep hole in the sea floor and turn it into something harmless? New research suggests the idea is not so far-fetched. David Goldberg, Taro Takahashi and Angela Slagle of Lamont-Doherty Earth Observatory published a study on the subject in the Proceedings of the National Academy of Sciences this week.

War Resister support protest at Peace Arch

Photo of protestOn my way back from Canada, I stopped for my usual visit to the Peace Arch on the Canada/US border. This year I was pleasantly surprised to find a protest in favor of US war resistors, and Robin Long in particular. For more details, see http://resisters.ca/index_en.html. Click the photo on the right for more photos.

Robin LongIn short, Robin Long is a US Army soldier who fled to Ontario in 2005. He has been in Canadian courts as one of the test cases for deportation. While the Canadian Parliament votes (non-binding) to allow US soldiers who have left the US to stay, the Prime Minister has different politics.

Here’s the Wall Street Journal article on Long’s deportation.

I was interviewed by GlobalTV, so I might appear in an online story there.

Great visit with some of the Canadian Trampleasures

Four TrampleasuresThree more TrampleasuresLast night I had a great visit with cousins in Delta, British Columbia, Canada.

Gary is my “fourth cousin.” He’s proud to be the oldest living Trampleasure in Canada, and the third oldest in the world (my dad beats him out by a decade, as does Colin in London).

I met two “fourth cousins once removed” and three “fourth cousins twice removed.” We had a great time talking about the family tree, how Canada got it’s name (a joke I’m sure they would have heard, but maybe it’s just a US joke), whether or not we actually made it to the moon, and the reality of the 9/11 events (let’s just say not everyone believes the US government tale).

The kids were pleased to see a Trampleasure from another shore (well, almost).  I had a great time. The visit gave me encouragement to do more family tree research.
