As my alarm goes off, I roll out of bed and head to the kitchen. My customary breakfast is a bowl of oatmeal with raisins and a banana, plus a glass of OJ. Time at the breakfast table with warm food helps me relax into the morning.
7:00 Bike ride to the train
On my bike and out the garage. My ten-minute ride starts through a local park, where I often see swap greetings with familiar faces as we pass one another. As I crest a small incline through the park, I am greeted by the glow of the sun behind the horizon across the bay. Now on roads, I soon trade hellos with the usual flagger at a construction site in the Bayshore. Another mile, and one small hill, and I’m at the Caltrain station.
On Fathers’ Day this year, I heard a sermon by Rev. Vanessa Rush Southern at the Unitarian Church of San Francisco that challenged member of the congregation to think of all the ‘fathers’ in our lives. As one who is not a biological father, and has only experienced a child’s early years with my granddaughter—both my stepdaughter joined my life when they were over 13—I was moved by this idea of celebrating the ‘unusual fathers’ in our lives. I reflected, and came up with five fathers I have had.
My first father, my biological father, is Bill Trampleasure. Bill passed away almost five years now, and he was with me my entire life. My second father was Jack. Jack was a PE teacher at my junior high (ML King in Berkeley), but I never had him as a teacher—instead Jack had a group of kids who went out running before school. My third and fourth fathers were Scott and Steve. Both these men were about ten years older than me, and I was involved in peace/anti-nuclear work with them for several years in my late teens/early twenties. My fifth father was Jose, my boss from about age 20-33 (with a four year gap in the middle). Continue reading “Happy fathers’ day to all my fathers”
I suspect most Berkeley residents don’t go to People’s Park very often, if at all. Even as one who grew up in Berkeley during ‘the sixties,’ I never set foot in the Park until I was a student at Cal in the late ’70’s. I suspect most people view People’s Park as a destination that they don’t find attractive. Sure, there is a reasonable collection of us who have given sweat and tears, and even blood, to maintain this land as a park, whether that be in the ’60’s as the park was created/reborn, or during the decades since, when the University attempted several times to fundamentally alter the use of the Park. But it is likely that the majority of folks in Berkeley have no strong connection to the Park.
So now, as its 50th anniversary approaches, I suspect that most folks in Berkeley see People’s Park as an ‘attractive nuisance’ at best, and perhaps a ‘dangerous eyesore’ at worst. So the current proposal—that includes 700-1,000 student beds, 75-110 ‘supportive housing’ beds, and ‘park/open space’ with “… an important element … design that will commemorate, honor and celebrate the history and the significance of People’s Park”—will likely be received by most folks as a step forward. I would like to offer, however, an alternative, long-term view of this proposal. Continue reading “Why building housing on Peoples’ Park is not, and will never be, a good idea.”
Try to complete each section on your own before you move to the next image. Each slide shows the answer to the preceding question.
1. First, examine the problem and determine the energy storage types involved.
This problem consists of a roller coaster which has a chain that pulls the car to the top of the first hill. The problem defines the system as frictionless (μ = 0), and insignificant air resistance. Before you go on, define the system, then draw axes for your energy diagrams at each point with a letter (don’t worry about the number of blocks of each energy storage yet).Continue reading “Solving ‘roller coaster’ energy problems”
In the late 1970’s/early 1980’s, I was part of a movement to convert the nation’s premier nuclear weapons developing labs (Lawrence Livermore in California, and Los Alamos in New Mexico) from labs that primarily focused on research in nuclear weapons to ones that focused on human needs.
Each third Saturday in September in California, the California Coastal Cleanup Day gathers thousands of people to help clean tons of trash from our beaches and waterways. The 2017 event occurred on September 16th.
OK, maybe I’m in the minority, but I really like Back to School Nights. I appreciate the parents taking time out of their busy lives to come in and get a sense of who is teaching their students.
Tonight was no different. Great parents, lots of appreciation expressed, and a few good questions thrown in (not much time in ten minutes to ask questions).
Unfortunately, as usual, the higher academic classes have higher turnout of parents. Why? I can speculate about amount of free time, ability to get off work early, etc. But in the end, I don’t think it’s anyone’s fault (I suspect that all parents want their kids to be successful in school), it’s just a reality.
Thanks to all the parents who did make it out (and thanks to all those who didn’t for trusting your students in my care).
I have been making many video tutorials for my science classes in the last few years, and some folks have asked how I create them. I have gone through a process of changes, so I thought I’d present the options I have used to create them.
