LIGO X
The LIGO Instrument Science Group at Caltech
Meeting time: Tuesdays, Noon, 2nd Floor West Bridge Conf Room (except during SURF season when we move to 3rd Floor SCR).
The goal of this group is to collaborate and discuss ideas for experiments to perform on the Caltech campus. We work on projects that are immediately applicable to the IFOs today, as well as future generations of interferometers.
Presenters are sometimes chosen in advance, sometimes chosen spontaneously, to present the experiments they are working on, experiments they plan to work on, or experiments which could be interesting for LIGO. All talks should be "chalkboard talks", i.e. no prepared slides.
Pizza
We often have pizza at our meetings.
If it's you're the Primary Pizza Person (PPP), or if you're the Backup Pizza Person (BPP) and haven't heard from the PPP by 11:30 am, call up Pizza Man - (626) 577-1135
- Get the Pcard from Julie. The billing address ZIP is 91125.
- It takes 45 minutes for pizza to show up. If it is possible, order the day before
- Order 4 large (or 3 if there is a small turnout expected) - these come with 12 (?) smaller slices (which is good)
- One pizza should be vegetarian. Also, the carnivores get antsy if there's not at least one pizza with some kind of meat / chicken.
- The favorites (but feel free to be adventurous!):
- "Meat Lover's Trio" (This is the most popular sort of pizza, people will be sad if you do not get this)
- "Mexican" (several kinds of meat)
- "Chicken Cilantro" (chicken and veggies)
- "BBQ Chicken" (chicken with lots of BBQ sauce)
- The favorites (but feel free to be adventurous!):
- Make sure to ask for an itemized receipt.
- Ask for sodas from the pizza guy, or buy 1 2-liter bottles of soda from the C-Store or elsewhere.
- Ask him to meet you across the street from Cahill (aka "The Red Building") on California...they know where that is
The address according to Google Maps is 1247 E California Blvd, Pasadena, CA 91125
- Inform the BPP that you've got things covered / reprimand the PPP for their negligence.
If you ordered using your own card - Keep your receipts - give them to Julie Hiroto, and she will take care of your reimbursement.
- If you used the Pcard from Julie, be sure to return the Pcard and the receipt (with an indication of the tip you paid) to Julie.
The Pizza List
We've had trouble lately with grad students remembering when it's their turn to get the pizzas. This is a big no-no, since it leaves the entire LIGO-X group grumpy all day. This list is the official place to look. In an effort to remind people, emails will be sent out weekly the night before the meeting, but grad students are still responsible for checking here, and should not rely entirely on the emails. (The script to send the pizza reminders is in /cvs/cds/caltech/users/jenne/LIGOX/LIGOX_Pizza_Reminders.sh /opt/rtcds/caltech/c1/scripts/general/pizza/pythonMailer/pyPizza.sh , and it runs as a cron job on Nodus. Feel free to edit it, especially the List.txt pizzaListParams.yml which holds the list of people to email reminders to...if the wiki gets changed, the List.txt also needs to be changed.)
