Jimmy World atCaltech - This Ain't NoKaraoke Contest

It is beyond me how wegot Jimmy Eat World to playhere. "What is a hot bandlike them doing at a schoollike ours?" is just one of themany questions answered inthis interview. I can't believeI got the chance to meet andinterview one of my favoritebands of all time: Dreamy!

In the hours before theirconcert, a bunch of students,myself included, were treat­ed to a IS-minute meet­and-greet with Jim, Rick,Tom, .and Zach in WinnettLounge, all possible thanksto Dima. They were all su­per nice, even when I wasall star struck and stuff. Ihad compiled a lot of ques­tions over the previous twoweeks, and I couldn't de­cide whether I wanted aninterview centered on mu­sic, or funny stuff, or stuffthat gauged how nerdy andTecher-like they were, soI put in a few of the best. Igot a lot of good responses,including the shocking storythat explains the title of thisarticle. Please enjoy.

We couldn't get an officialinterview where I sat downand talked to them all atonce, so I had to ask each ofthem separately.

Encounters with ZachLind (drums)

CK: So you guys play vid­eogames? I heard you playalot of Battlefield 1942.

ZL: We do, yeah we playthat. We playa lot of video­games.

CK: How many hours doyou guys spend playing?

ZL: Well, we probablydon't playas much as theaverage geek in college,but like we probably play alot for how old we are, youknow.

CK: Laughs. Oh, I don'tthink it's age related...

ZL: Yeah, I don't know.CK: Uhmm so... Inter­

view gets sort of awkwardhere. What's your eyesight?

ZL: I have really goodeyesight, whatever that is.

CK: Hey, that's good. Soyou're a straight A student,right?

ZL: No, I was never astraight A student. ..

CK: Whatever, it's cool;none of us are, either. Timeto ask new questions... Soyou're playing in Australiaafter a few more shows in

states. How many timeshave you guys toured there?

ZL: This is our 3rd timegoing to Australia. It's re­ally cool.

CK: I know you guys hadfun touring in Japan, be­cause the crowds get prettycrazy, but how does Austra­lia compare?

ZL: Uhh, it's a lot like theStates I guess. Japan andAustralia are really differentthough; you can't comparethose two.

CK: Cool, well good luckwith tonight's show andgood luck with your tour inAustralia.

ZL: Thanks.

Conversations with JimAdkins (lead guitar/ leadvox)

CK: So what's the lasttechno gadget you boughtfor yourself?

JA: Uhmm... hmm... lat­est techno gadget. .. Thinks.

CK: I'm just trying tomeasure your nerdiness incomparison with the ste­reotypical Tech student.Like uhh... you know, 'howmany hours of video gamesto you playa day?', 'what'syour eyesight?' , blah blah.

JA: Uhmmm... latesttech­no gadget I bought was ... atube distortion pedal by a~ompany called· Metason­lCS.

CK: Yeah, I don't have anyidea about what he's talkingabout. .. Okay, sounds cool.

JA: Yeah?CK: Yeah...JA: It's kind cool, like

they make stuff out of tubesthat were never designed foraudio... stuff.

CK: Sound engineering,that's awesome. How's itdifferent from the other dis­tortion pedals that you havealready?

JA: It's ... uhh it's got areally high output, so yougotta be careful, 'cause youcould actually break stuffthat you use it with.

CK: Wow, that's cool!Wow, I sound stupid... oh,I think I'll have to ask youmore questions later, 'causeI'm sort of holding the lineup. Is it okay if I come backlater?

JA: Yeah sure.--To be continued. (Not

really.)--

Adventures with Tom Lin­ton (guitar/ backup vox)

CK: So I'm trying tocompare you with the ste-

reotypical geek at Caltech,and I just wanted to knowwhat your favorite science

school was.TL: Uhmm. .. probably

biology.CK: Oh really? That's

cool, I just changed majorsfrom Bio to Mech E-uhhmechanical engineering.

TL: Cool.CK: I also have some

other questions, this is un­related, but what's the worstyou've ever screwed some­one over?

------ Insert awkwardness-

TL: Uhhh, What's theworse I've ever screwedsomeone? Uhh...

CK: I'm realizing that thiswas probably a mistake toask. You don't have to an­swer that if you don't wantto.

TL: Uhmm.. .I'm trying tothink. Thinks for a while...

CK: That r--­meansyou'rea good per­son, really.

TL: Yeah,I don't thinkI've ever re­ally donethat. Laughs.

CK: That'sreally good.I'm glad youcan't answerthat ques­tion.

TL: Yeah,I've neverscrewed any­one over.

CK: Hey,that's good;it's a loadedquestion, re­ally. Ummwhat about,what inven­tion did youwish you hadthought of?

TL: Thewheel.

CK: Thewheel?That's a cop­out answer.

TL: What?Laughing.That's agood inven­tion ...

CK: Al-right, alright,it's a goodinvention. SoI heard youguys are likehuge BonJovi fans,

and you go to karaoke andsing, so what's your favoritekaraoke song to sing?

TL: Yeah, it was Jim'sbirthday a month ago, andwe went to a karaoke bar inChicago. And uhhh, well,we've gone to karaoke barsbefore, and when we getthere no one really wantsto go up and sing. So whatI did was that I went up andpicked all these random andreally bad songs, like UglyKid Joe, and I don't know,whatever songs ... -

CK: --like the "Cat's Cra­dle" cover?

TL: Yeah, yeah, just so thatpeople have to go up thereand Zach went up - Zach'sthe Bon Jovi fan - and hedid, "Dead or Alive."

CK: Nice, nice. Hey wait,so like, you guys go out tokaraoke, but no one wants tosing? That's kind of weird.

TL: Yeah, well people get

nervous, you know?CK: Yeah, but why do you

get nervous though? Youguys are on stage a wholebunch. But in front of eachother, is it like, 'oooh shy'?

TL: Haha, you know what?Actually, about the time wewere recording Futures,Jim went over to a karaokebar that was right across thestreet from our hotel. And Iguess they had, "The Mid­dle" on the karaoke menu.There was also a contestthat night, and Jim sang [hissong] "The Middle"--but helost! Laughs.

CK: Oh noooo... that'sterrible. That soo ... weird.

TL: True story, but kindafunny.

CK: That's a good story.Hey so, I heard you likeplaying videogames, yeah?

TL: Yes, I just got the X­box Live.

CK: So how do you like

Overall, I'm pretty happythat Caltech gave thisprivate concert and I hopethat they can do more in thefuture. Thank you to JimmyEat World for giving us anawesome concert, and thankyou to ASCIT and everyoneinvolved for the wonderfuljob they did. I had a greattime, and I'm sure that thisopinion IS shared amongmost all of the students whoattended.

RV: Thanks so much forthe concert. Here's your din­ner. By the way, the reporterforgot to ask you a very im­portant question.

Manager: Sorry, no way.It's too late.

RV: But it's only one ques­tion.

RB: Where is she?RV: Oh well, I was just

going to ask you for her.RB: Okay, what's the

question?Manager: No way, you

can't ask them. It's alreadyover.

RB: But what's the ques­tion?

RV: Why did you chooseto play at Caltech? Why didyou agree to play here?

RB: Ooh, that's a hardquestion... Well, it soundedlike it could be a fun con­cert.

RV: Did you have fun?RB: Yeah, it was awe­

remedy that later.Soon after meet and

greet ended, their openingband from San Diego, TheJade Shader, took stage.They were well received bythe crowd, with their songsabout pirates and Emergen­C antics. The Jade Shaderhad been on tour with themin the past, but they weren'tslated to follow JEW on thenext leg of the tour to Aus­tralia with Green Day andMy Chemical Romance.With the end of The JadeShader's set, the crowd waswarmed up for when JimmyEat World took stage.

Having seen them play livea total of three times, twicein high school and once hereat Tech, the concert five lastSaturdays ago was worldsbetter than the other times.This time, I got to interviewthem too, but still the judg­ment stands. I'd say thatthe concert venue makesa huge difference; the firsttwo times I saw them playin a sports arena setting,and I had sucky nosebleedlawn seats. I felt like I wasat a lame sporting event thatcosted me too much to sittoo far away. A nice intimateconcert on the lawn was eas­ily the best to which I'vebeen. They played all theirsingles off of Bleed Ameri­can and Futures and a fewof the lesser-known songs,including one they only typi­cally play in concert. The setincluded an encore as well,which was nice.

At the end of the concert,I was still bummed aboutnot getting to completemy interview, especiallybecause I didn't ask themthat last question. I practi­cally begged everyone whoI thought could help me getbackstage again with verylittle success. However, Idid get lucky when I asked a

Thank you! !!"I had originally meant it tosound less corny or retardedbut whatever. Jim smiledpolitely and their manager,who was being a jerk, prac­tically pushed me out thedoor.

So, even though theirmanager could have been alittle more generous, I stillgot an interview of sorts.Although, I had forgottento ask them one key ques­tion, "Why did they chooseto play at Caltech?" I shouldhave started the interviewwith that question, but myapologies: I'm an amateur.You may also notice that Ididn't ask Rick Burch (bass)any questions, but I will

Discover the mechanism controlling the mass ohhe proton•The mass in-flow rate into the neutrino depends on the enveloping sphere

diameter which is the ether mean free path and thus is independent of the variablemass of neutrinos.

• Energy conservation of the final condensation requires an extremely large thrustforce (mega-newtons) applied to the neutrino condensed assemblage.The thrust is

produced by the surrounding background.

• Collisions between two neutrinos can result in a neutrino taking a circular path.

• One value of mass can balance the centrifugal force to the thrust force and have

an angular momentum equal the neutrino angular momentum.

•This mass is the mass of the proton.

•The disturbance close to the proton makes up the short~livedparticles associated

with the proton.

•The disturbance at a long distance from the proton is the electro-magnetic field.

Bitches is Hoes is a collectionof rants about the changes that arehappening around Caltech. Manypeople complain that these chang­es cause this place to become lessCaltechy. We have no idea whatthat means and we do not have anyidea what those people are talk­ing about. We are here to pointfingers. We are identifying theobvious examples of idiocy thatplague our community. These arethe cowardly acts committed bythe administration because theyare afraid to get sued. These arethe failings of different so-calledcampus services because they areafraid of budget cuts. These arethe students who sycophanticallyadhere to the administration'sweak excuses. And so we labelthem as "bitches." They are as ef­fective as a blind, spayed dog withits teeth knocked out and a gianttumor coming out of its nose.They have sold out by sacrificingthe efficiency and quality of theCalteeh experience for an illusionof politieally correctness and safe­ty. Hence, bitches is hoes.

On another note, don't try tostick us with libel. Everything inthese articles is true.

so lighting is an im­portant consideration in thiswhole business," he says. "Iuse different types of col­ored lights shining throughthe crystals, so the ice struc­tures act like complex lensesto refract the light in differentways. The better the lighting,the more interesting is the finalphotograph." The structuresof snowflakes are ephemeral,so speed is needed to get goodphotographs. Within minutesafter falling, a snowflake willbegin to degrade as its sharperfeatures evaporate away. Thecomplex structures are createdas the crystals grow, and whenthey stop growing, the crys­tals soon become rounded andmore blocky in appearance."When photographing in thefield, I first let the crystals fallonto a piece of cardboard,"says Libbrecht. "Then I findone I like, pick it up using asmall paintbrush, and place iton a microscope slide. I thenput it under the microscope,adjust the focus and lighting,and take the shot. You need tosearch through a lot of snow­flakes to find the most beautifulspecimens." Libbrecht findsthat observing natural snow­flakes in the field is an impor­tant part of his research, andnicely complements his labo­ratory work. "I've learned agreat deal about crystal growthby studying ice, and have got­ten many insights from look­ing at natural crystals. Natureprovides a wonderful varietyof snow crystal types to lookat, and the crystals that fall
