Christmas parade on Black Friday

Every year on Black Friday, my lion dance association would participate in the Liliha-Palama parade. Why a Christmas parade has two different lion dance groups performing isn't the problem. The problem this parade was the massive amounts of wind we had this weekend. The Force of the Wind (let's call FTW) was strong enough that it almost overcame the force I applied to my Lion (FML). AS the FTW increased I found it harder to keep my lion head up with sufficient FML. So in response to the FTW I applied a rotational force in order to maybe get some tangential acceleration in the desired direction. The tangential acceleration force plus the FML was enough to overcome the FTW and allow me to move my head sideways against the chilly winds.



Lesson learned: If you raise a kite-like object, whether or not it has mass, it will behave like a kite and catch the wind. And I really wanted to got to the Cicadian rhythm presentation.:(

Away to Maunalani Nursing home

This weekend I went to read stories to the elderly with Iolani storytellers (Spoonful of Sugar)- why we read children stories to sleeping, Japanese-speaking, angry elderly is beyond me. The drive there is actually pretty precarious. The path I took up the mountain was Wilhelmina Rise, which was a pretty steep straight road. Only around the top did I notice that the sign for Sierra Drive was reoccurring very frequently. Only when I arrived at the nursing home did it hit me that Sierra Drive was a smoother, winding path up the mountain. Feeling rather dumb for taking the steeper, narrower path, I was reminded by the physics term of work.
Work in Physics is defined as the amount of force used over a distance. I almost did the same amount of work going up the steep path than I would've on Sierra road, because the increase in force on the stupid path is compensated by a decrease in distance traveled. Moral of the story is, if you want to punish your grandparents and put them in at Maunalani nursing home(or any nursing home), take the flatter way up the mountain to avoid climbing it.

go around not up

Real Life LAB

On Friday after we finished the rod lab, I hung out in the room to kill the remaining 10 minutes of class. I mean how much homework could I have significantly done in 10 minutes. I started trying to do the ruler lab with the foo rulers, but realised eventually that the non-flatness of the rulers prevented them from stacking perfectly. I then turned my attention to the meter sticks. No one was using them so I grabbed the three that were out and the remaining nine to attempt the lab in real life. AS I started balancing the rulers, each bottom one meeting midway of the top weight, i eventually realised that this was going to be epic! I started having the distance, but soon reached the point where the rulers couldn't be aligned up perfectly with the half, so I did what every good physicist does. I eyeballed it. When I finally stacked up the ten rulers to the utmost balance, I started pushing the bottom ruler out slowly. A centimeter and a time. After several minutes, I reached the gold metal part of the ruler and couldn't push it forward anymore without risking tipping over my beautiful tower of rulers. So there stands my creation extending at 172cm off away from the table!

Luce physics

First of, I want to thank all of you who came to support IDP's production of A Commedia of Errors! We raised over $4.00 x 10^3!!! But for those of you who didn't come, Ihopeyoufallinapitanddie, but anyways you guys won't understand what I am about to say, or the title of the post for that matter. In the play, Dromio of Ephesus has a large kitchen wench called Luce. When the two Dromio of Syracuse ends up guarding Antipholus of Ephesus's door, The two Dromios have a battling out over entrance. When, a midst the arguments, Luce shows up inquiring to know what's going on, she mistakes Dromio of Syracuse to be her husband and the Dromio outside to be a lolygagger...lollygagger...lollygager...trickster.

In this picture Luce attempts to bar the door shut using her extremely rotund hindquarters. As she thrusts out towards the door, she has to remain stationary, so she has to thrust out her huge "assets" as well. This obeys the conservation of momentum, since the slightly lighter upper side moves in the opposite direction and faster speed than the lower portion in order to keep the overall momentum 0.

As seen in the equation Mb(Vb)+ Ma(Va)=0
Mb= mass of the arse, Vb= velocity of the hindquarters
Ma=Mass of Luce's "assets", Va= velocity of Luce's "assets"

Halloween knife trick...

For those of you who are among the many that didn't come to the Homecoming dance on Saturday, probably due to trick-or-treating, I brought a...*pleading fifth amendment*. Anyways this... thing was used multiple times that night, which almost had a full moon by the way. After stabbing multiple people, one of the weaker dying ones saidd that the "stab" really hurt. It didn't bother me then, but now i have to blog about what i did this weekend. So in the terms of impulse, there was a larger J on the person- let's call him Freddie- due to the fact there was a larger force applied in the same amount of time. Now recall J=F*T , that means Freddie's liver and heart experienced a rather larger J causing him to experience more pain. In this picture you will notice blade is still outside of Freddie mailnly because of the smaller F applied, but in the second one the knife made a completly inelastic collison with Freddie resulting in his immense pain. The larger force spread its momentum to the more of the other cells resulting in freddie experiencing more of this pain sensation.
