 Volleyball Concludes Statistically Strongest Season Ever www.gocaltech.com/sports/wvball/2018-19/releases/201810298nimkvVetrivel Receives SCIAC Character Award  Vetrivel has been a team captain for the volleyball team each of the last three seasons and has improved statistically every season culminating this year as the program's third. She has been the Caltech Student Body President for two years, had summer internships at Microsoft twice, and has been a constant as a positive spokesperson for the volleyball program. This is the first year the SCIAC Character award has been given out and is awarded to one senior athlete per year who demonstrates the character and values of what it means to be a SCIAC and NCAA Division III athlete. www.gocaltech.com/sports/wvball/2018-19/releases/20181029lo2uoe |

I taught a section on ODEs or Diff EQs (pronounced "diff-EE-q") in each of my final two semesters in grad school. Ah...what memories...
In the back flap of the textbook I used, I have scribbled in pen:
𝛿(t)=0, if t≠0
I have no idea what this means now. LOL!

No, Dirac delta function. It's supposedly very important. LOL! Don't remember why. |

I love CalTech's unis! My favorite combination: orange and black (white).

D(t)=0 means nothing changes with respect to time. But only if time does not equal zero. Basically, you are providing a jolt at a specific instance (t=0) but not any any other moment of time. LOL! All you did was recite in words what is overtly shown in the mathematical formula! LOL! |

My #1 and #2 sons didn't get into CalTech.
#1 son ended up at Duke and #2 son ended up at Northwestern.
I made no effort to get them into CalTech. I'm a firm believer of accomplishing things on your own merits. Except for investments. You should always try to get insider trading tips. Also, for sports betting, get tips from your bookie.

One way to analyze something is to give it an impulse and then see what happens. Like striking a tuning fork and then measuring what frequency it hums at. The trick is that an impulse actually contains energy at all frequencies, but the tuning fork will only respond to the frequency it is tuned for.

This give me flashbacks.... “Problem 8, find the impulse response...” We do that in emissions. Because you have a situation where every year there is more and more emissions, that accumulation controls the model output. Sometimes it's useful to understand the response to just a single input, so you can check things like whether you have modeled the sinks in the system correctly. If you input one year of carbon into the model and it never goes away ever, then you don't have the sinks correct. |
