I need physics help! hahaha.
anyone with any tips on converting computations. i forgot all that stuff.
like velocity=distancextime or something, stuff like that. anything will save my life. my professor does not know how to teach and I dont get my textbook in the mail til like, next week so I need to find some crazy research somehow.
Help this poor student! I wanna cure cancer! :(
No hot chick in the class you can study with?
You were close..........Quote:

Have a good one!:s4:
V2 = V1 + a(t)
V2 is the final velocity V1 the start velocity a is acceleration t is time (more accurately the change in time)
x = V1(t) + 0.5(a(t)2
x is the distance travelled btw the t is squared in this equation
also the biggest physics formula of them all (although it is forces and not kinematics like above)
F=M(A)
F is the total force M is the mass of the object and A is its acceleration
OMG WUT LOL
What??? why cant we just keep things simple?Quote:

Doesn't get much simpler really :)
I learned loads of these formulas at school (2 or 3 years ago) and have neither remembered any or for that matter needed any since leaving Einstein, Newton and Co. have got a lot to answer for LOL

P.S. there is a little brewery in Hertfordshire that makes Newtons cider, bit of a coincidence or what?
Or in the case of hydraulics and pneumatics.............Quote:

Have a good one!:jointsmile:
HAJK,
Psycho4Bud is the resident hydraulics/physics expert around here. Not me. I have had one semester of very basic college physics about 100 years ago, and I'm stilll trying to erase those memories from my mind. Now if you have any questions about human anatomy or physiology, medical microbiology, or medical biochem, that's more up my alley . . . .

but i got some good stuff today after work just now. i got like all these formulas.
like..
d=v/m for density
m=dv for mass
and v=m/d for volume
those are the basic ones i needed for this lab im doing right now. were just measuring volume and density and stuff for these iron and copper rods. everyone wanted me to do their work because im a master of the triple beam scale. ill leave that knowledge of mine to your own imagination ;)

go spin in circles whilst holding a bucket of water and relish in the fact that you are recreating the earths gravitational pull. its really amazing, its just hard to put into calculations.
Coelho is the fellow you want to ask about these questions. He knows his physics and gave me a very nice explanation for my galaxy-spanning iron bar.
Dude go to the school store, and find the tall spinning stand with all the laminated study guides. The physics one has alot of the calculations all right there.Quote:

By using both sides of the brain you are creating a more stable frame of reference, and physics will be much easier. I slept all through math classes my whole life, never even touched a calculus or Trig book before stepping into my College Physics course, but because he described every concept with a very real world approach, the calculations not only made sense, they fit perfectly.
halfassed, become a cryptozoologist. If I had to be any type of ist it would have to be in cryptozoology
I have a medical question-someone I know was diagnosed with neuropathy-the doc ordered some bloodwork with the following tests:
-Fasting B12
-ANA
-GM1 Ganglioside -IGg, Igm
what's he looking for?
I really appreciate your help and thanks.
A fasting B12, or ??Schilling test,? looks at how well B12 is absorbed by the body. The patient fasts overnight and then has a vitamin B12 injection and takes radioactive-labeled vitamin B12 tablets. The amount of vitamin B12 that comes out in the urine is measured. B12 and folate deficiencies can cause certain types of anemia or neurological symptoms such as neuropathy.
The doctor may have also ordered fasting blood-glucose testing, too, to check for diabetes, which can also cause neuropathy (but usually only after someone??s been diabetic for a long time).
The ANA test is an antinuclear antibody blood test that can detect certain autoimmune diseases such as rheumatoid arthritis or lupus.
A GM1 glanglioside test looks at the level of anti-ganglioside antibodies (AGA) to GM1 ganglioside in patients who have motor neuropathies.
IgG and IgM (along with IgA) are other types of immunoglobulin antibodies that show up in bloodwork when people have some sort of autoimmune disease or sometimes also other types of blood-related disease.
I was able to find out all this testing info on my school research sites. I'm not trained yet in what they're all used for, but it sounds like the doctor who ordered those tests was trying to nail down the cause of any neuropathy and rule out a vitamin deficiency or possible diabetes, then see if he could determine whether an autoimmune disease process such as rheumatoid arthritis or lupus was causing your friend's neuropathy.
Mmmmm....Smarties.....
Thanks Birdgirl-hmm interesting..I should have given you more background on the patient to give you a better picture of what's going on...she's a 70 y/o very pleasant lady who was diagnosed with uterine cancer and was treated with a series of radiation and chemotherapy (Taxol/Carboplaitin) treatments. Prior to this, the patient had no signs or symptoms of neuropathy. The patient noticed that while undergoing the chemo treatments, her feet began showing signs of numbness and pain which traveled up to her calves as the treatments continued. We're trying to find out how and why this occurred and now that her treatments are concluded, how much feeling will return and to what degree.
The doc thinks it might be related to the radiation treatments and not the chemotherapy, but the patient insists this began with the chemotherapy. She has no history of diabetes. I'm trying to see how these tests correlate with her present condition.
Or is he checking for something else?
the distance ones just remeber a triangal
m
________
d x v
cover up the one you want them either multiply or divide
is the one for pressure in a closed system
P1 P2
_____ = ______
A1 A2
dude they ain smarites there shit erm sherbert, like love hearts. fuck i love sweets. erm they aint smarties.
Remember, I'm still a student and certainly not a full-fledged doctor yet, but based on the further information you provided above, it sounds likely that the doctor was ordering those blood tests up in your previous post to simply rule out other causes of neuropathy, such as an automimmune disease, and confirm that her problems are a result of the chemo and/or radiation.Quote:

It makes sense to me that the radiation could have caused her neuropathy since it would have been aimed at her pelvis and could ostensibly have affected the nerves that issue from the the bottom of her spinal cord and stretch down into her legs and feet. I'm not sure it matters a whole lot whether her neuropathy happened as a result of the chemo or radiation. That is, knowing which one caused it isn't going to change the fact that she has it now. With luck, those nerves will get better and heal up and she'll feel better. Nerve healing takes a lot of time. That'll be slow going, especially for someone who's 70. Hope she has a good recovery!
Why, thank you!! :thumbsup::DQuote:

But im not the only one here... im sure HAJK already got the answers he needed... anyway, im always available for any questions... :thumbsup:
Thanks again Birdgirl-I know your not a doc yet but I wanted your take on it. And It's kind or amusing at the same time..."So where do you get your medical information...WebMD?" "Hell no, Cannabis.com." :):thumbsup:;)
lots of smart folk round here.Quote:
