If you want to know your score, email me
being sure to delineate who it is!!!
and ill respond...
OK, lets wrap things up.
There are some details on the regents results etc
below.
Typically, I arrange grades such that no one winds
up with an 89. So, if your year-end grade is 89.0
or above I did what was necessary to have it round
up to 90. However we had 3 or 4 students this year
that wound up with an 88.4 or 88.6, and I couldnt
get those to 90, so there will be a few 89's this year.
As for some awards:
Most "girly" reaction to the sight of a beetle
in my hand during the Regents:
Mr Seipp (it was shocking)
Most unlikely to win a spelling bee award:
a tie between Taylor Dean for "virtically"
and Jeanne Cloyd for "Jules"
Worst use of a protractor, a tie between two students
who lost a point because they drew a light ray with angle
to Normal of 16 degrees when it had to be between
17 and 21!:
Laura Bauer and Pam Zazzarino
The "why are you leaving so early when you have
9 or 10 MC problems wrong" award:
Robert Muth
The owner of a clearly busted calculator award:
Meghan Gallucci for taking 46.5 dividing by
5.3, and getting 23.25!!!
Question that almost resulted in several large
blood vessels to become severed within the
skull of teacher:
The one where you had to draw the field around a
single NEGATIVE charge and about 10 of you drew
lines AWAY from it!!!!! and we wont even get into
Dylan Walker's monstrocity on that one.
The "had the right answer" but mysteriously crossed
it out and circled a bizzarre answer" award:
Calvin Dinio
Most points lost to not putting units:
Jake Jordan(but not many!)
and during the year:
Most fun to torment:
Ibsen and Morris
many runner-ups here
Least variation of diet:
Lu
Most strange looks at teacher:
Vigliotti
Most unhealthy obsession with aging or deceased
singer-songwriters
Fitzpatrick
Most likely to discover dark energy
Cali
Most likely to doze off during class
walker and steiger
Most likely to be tapping or tamping anything
available:
Walsh
The best thing to do this Summer award:
a tie
1) go to hulu.com and then
"cold open of the first show"
for
The tonight show with Conan O'Brian....and enjoy
2) Listen repeatedly to the theme (NOT the Linkin park
one) from Transformers 2
3) Watch Appollo 13 and The Last Samurai
4) watch any science Fiction movie and critique
it in your mind now that you know how the laws of
the Universe work.
OK< I think Ill wrap it there,
I have to say I love you all (I know Pavelock and Ibsen
are rolling their eyes right now)and I wish you
all the very best in the future.
Though I still insist it was a slightly easier
test than it normally is, the cumulative average
of 90 may never be matched again, and for that
I thank you(though you've condemned me to a future
of failing to match that every year!).
Upon further review there were about 8 grades
that changed,
Of the ones I emailed, Colin, sorry you dropped a point
and Joe P you went up one.
With the new scores I technically saved one sandwich
but Ill be nice and give Kevin his anyway

L Messina 3 Quiznos from yellow class
K Brogan
Yelow average was 87.5
Highest was Schepis witha 98(but no quiznos for you
amigo!!)
red came thru with an average of 92.2
the new highest ever!!!!
Red
Dennis 99, Sayegh 100 (congrats)
Fitzpatrick 99, Duncan 99 Sallah 99
Carey, Kramer, Dorney 98
Green came through with an average that was 89.9
resulting in an overall average for all three
classes of 89.92!!!
That is BY FAR the highest ever. Maybe we can find
a total of 6 points to get to 90.00 but probably
not.

Mrdjenovic and Miccarelli 98

Martin Quiznos
Petit (ouch that hurt)

(a lot of very near misses!)
Im thinkin Ryan got rooked!!!
This must have been a slightly easier test, but I
think there is less of a curve, and frankly, if
your score is over a 90, there is NO curve anyway.
Some notes on Lab six.....
1) Several of you lost a few points due to not
putting units
2) Liz, the "throw-back" type style was kinda neat
3) Morgan!! the angle must be measured relative to
the Normal!!!
4) The following individuals did not clearly demonstrate the ability to use a protractor.
You might want to practice before the 24th!!!

Twenty Five ways to intimidate your professor.....
Bring a light bulb, hold it over your head whenever
you have to answer a question
Sit in the front row and spend the lecture filing your teeth into sharp points
Wear earmuffs, every few minutes ask the professor to
speak louder
Ask whether the first chapter will be on the test,
if the answer is no, rip the pages out of your
textbook
Become entranced with your first physics lecture,
declare that you intend to pursue a career in measurement and units
Sing your questions
Page through your textbook scratching each picture
and sniffing it
Hold up a piece of paper that says in large letters,
"CHECK YOUR FLY!"
Sit in the front, sniff suspiciously, and ask the
professor if he's been drinking
Feign an unintelligable accent and repeatedly ask,
"Vet ozzle haffen dee henvay?". Become agitated
when the professor cant understand you
Leave permanent markers by the dry erase board
Shout "WOW!" after every sentence
Watch the professor through binoculars
Relive your junior high days by putting chalk in
the erasers
Ask to introduce your "invisible friend" in the seat
beside you, and ask for one extra copy of each hand-out
When the professor turns on his laser pointer,
scream "AAAGH, MY EYES!"
Correct the professor at least ten times on the
pronunciation of your name, even if it's Smith,
claim the i is silent
Sit in the front row reading the professors graduate
thesis and snickering
In the middle of the lecture, ask the professor
if he believes in ghosts
Laugh heartily at everything the professor says,
snort when you laugh
Bring a typewriter, use it to take notes
If it's a math lecture, claim the professor misspelled
pi
Come to class wearing the same outfit as the professor,
call the professor a copycat
When the professor asks a question, raise your hand.
If the professor calls on you, point to someone
else and say "He knows"
Wear X-Ray specs, every few minutes ask the professor
to focus the overhead projector

22. When in the influence of a magnetic field, a nail will lose its induced magnetic properties when the external field is removed.
25a. The magnet causes the protons in the hydrogen of water molecules to align.
25b. When the radio wave pulses are discontinued, the protons return to their original orientation, emitting a signal when they do.
25c. Diseased tissue contains more water than healthy tissue, thereby producing a stronger signal.
26a. Power loss goes as the square of both the potential and the current. However, it oges directly proportional with the resisitance at high current, but inversely proportional with resistance with high voltage.
26b. A step up transformer increases the voltage in the secondary. However, the current is reduced. This is due to the conservation of energy.
26c. A varying magnetic field is required to induce a voltage in a conducter. The magnetic field about a conductor with direct current is constant.

18. rsonance
19. C
20. 2.5x10^9Hz
21. The Doppler Effect is tha apparent change in frequency due to the relative velocity between source and observer.
22. A radar signal is sent toward the storm. The reflected wave is recorded from the strom. The comparison of many of these reflected waves would reveal a shortening time of return, indicating the storm is approaching.
23. .315s
24. As the motorcycle approaches the front (1st) jogger, the fronts of the sound waves will be foreshortened because of the relative motion of the cycle-jogger. The wave fronts reaching the jogger are interpreted by the jogger to have a frequency higher than the actual frequency of the cycle sound. The jogger behind (2nd) the motorcycle will make theopposite observation due to the lengthening of the wavelength due to the increasing relative distance.
