Debridement is hell, isn't it? Nothing like letting someone skin you alive a little bit each day, day after day after day... You're right. That was much worse than the burns.

Not SLUGS!!

Double Bullshit. As I've stated too many times already, that equation is obvious to any engineering or physics student. If you, or Kallend, can't recognize it as such maybe you should check the wants ads. I heard McD's is hiring. This is DZ.com, not MIT. Sure it's recognisable and sure we knew what you meant. However, as you wrote it, it did mean that 32.2 slugs equals 1 pound mass, which is also a valid equation. Why the hell would you ever want to rely on someone correctly interpreting what you wrote when you could put it beyond any doubt with a mere 6 additional keystrokes? Just think, for those 6 easy keystrokes you could have saved yourself an additional page of explanation. So if you think about it, being precise really would have been a more economical way of expressing yourself But not near as much fun. Kallend read my post. He had two choices. 1) Ask first and confirm whether or not there were units attached to the 32.2 or if it was strictly a scalar or 2) send the following meassage... Instead of asking for clarification he decided to write an insulting reply. I may not have my degree yet, but I do have thirty years of working with designers, engineers, chemists, and the man on the shop floor doing the fabrication, much of that time as an interpreter between the two. When someone had a question about a measurement or calculation, they asked. They didn't just jump up and start insulting people. To say I don't know what I'm writing about is a pretty big judgement for someone who has never met me. All of the clients I dealt with, which included several major cities, U.S.D.O.D., CIA, FBI, Bereau of Mines, Anheuser-Busch, several foreign countries, all branches of the military, and all major explosives manufacturers never ONCE did they say I didn't know what I was talking about. They were very pleased with the work we did and we had a good working relationship, to the point where we were called by the FBI on 9/12/01 asking for our input concerning storage and transport of explosives. But Kallend Almighty knows more than all of them and felt it was easier to call my intelligence into question than to ask for clarification.

'biner not boner...sheesh! Imagine how that would look? Walking to the apartment with 2-3 grocery bags hanging from....

Tru. Very true.

You do realize that graphic puts my percieved ablity and perceived score both at app. the 75th percentile, and the actual score in the 90th. Thank you for the compliments!

Dig dig dig... Your attitude reminds me of another professor I know. He also redefined what PhD means.

Kallend assumed it was as it was written, a dimensionless number. Since the equation was written perfectly to give the result of 1 pound mass why assume it would be anything else? First we'd have to assume you were trying to get a force, then we'd have to assume you were using a consistent system of units (and missions to Mars have crashed for that reason alone). Why let ambiguity creep into an equation when you could have put exactly what you meant simply by typing ft/s^2? Because I mistakingly believed he was intelligent enough to assume I was referring to gravity. As I said before, this is not a classroom. People abbreviate all the time, omit things that are assumed. What else could 32.2 be taken as? If there is another constant that has has 32.2 as a scalar I would be happy to know of it. Kallend should have readily recognized the equation as being of the form of Newton's 2nd law. Newtons 2nd is used to state the relationship of mass to acceleration to force. As such 32.2 is obviously gravity. If he failed to pick up on that then I don't know what to say. But don't blame me if he missed it. Any freshman student of math, physics, engineering, etc. is expected to recognize certain equations without being told what they are or what they represent. If he didn't recognize it as such, then maybe it is HE that needs to study a bit. If he wants to insult me, fine. But he has no call to bring into question the credentials of my prof who he doesn't even know. I did talk to my prof today and he restated that he pointed out the entry in Wik as being misleading, not as a total error. Same thing he said yesterday. There are a lot of things in life that don't need clarified every time they are stated. Speed limits in the US are assumed to be in miles per hour. Fuel mileage in a car is assumed to be miles per gallon. Wing loading is pounds/ft^2 A persons salary is assumed to be either dollars per hour or dollars per year. Easy to tell apart...not many people would take a job paying $15/year, nor do many people make $35,000/hr. (Though some do). In physics and engineering, when Newtons 2nd is used 32.2 would be rocognized by most people as gravity. It is only dimensionless if someone fails to make the connection.

Like a lot of people I have a small 'biner on my keyring. When I go grocery shopping and get back to the car I take the 'biner off my keyring and put it through the handles on the plastic grocery bags. This holds them together keeping them from falling and spilling their contents all over the place. When I get home it makes it easier to grab the bags, no fishing around among rolling cans of soup and boxes of pasta trying to find those elusive handles.

Yes, quite ironic indeed.

If you didn't know 32.2 was ft/sec^2, what the hell did you think it was??? Chickens? Duck ankles? This is DZ.com, not one of your physics classes so even if you do require your students to specify units in that equation everytime they write 32.2 or 9.8 don't expect eveyone here to do so. Use the lump on top of your shoulders and figure it out...it's only common sense. If you're not sure, then ask.

You didn't specify any units for 32.2, in which case it is dimensionless. Mass times a dimensionless number is still mass I didn't feel it was needed to specify that 32.2 was ft/sec^2. I assumed that a physics/engineering professor would know 32.2 wasn't miles/day^2. 32.2, as well as 9.8, are numbers which should be very familiar to a professor and wouldn't need clarification when used in Newton's laws. jakee is 100% correct and you are wrong. If you were in my physics class, your score would be moving into negative territory right now. You can't give up while you're ahead, but you can give up before you get even further behind. Do you argue with your medical doctor about medicine, and with lawyers about the law? If I found myself in your class I would drop. I expect my professors to know Newtons' laws. If a doctor told me eating ramen noodles would cure a broken leg, yes. If a lawer told me to ignore the car with flashing blue lights on top and just drive faster,yes. And if a professor tells me that Newton was wrong, yes, I'll argue with him too. You're not the first professor I have pointed out a mistake to, but you are the first to deny it. Just for clarification, none of my professors require to specify the units in that equation...they are intelligent enough to know what they are without being told. The only place they want to see them is in the final solution, if needed. And I did admit I was wrong, more than once. At least I have the integrity to do so.

And I admitted as much. Crow tastes nasty. Kallend, I am surprised. You are saying Newton's Second Law is wrong? Several hundred years of scrutiny have proven that F=ma is fact. In case it's been a while since you read up on the subject let me remind you... F=ma where F is resultant force, m is mass, and a is acceleration. Applied to our equation in question, slugs is the unit of mass, gravity is the acceleration, and the weight is the force. Slugs(m)*gravity@32.2ft/s^2(a)=weight in pounds(F) It's pretty plain and self explanatory that in this equation pounds is weight and not mass If you wish you may at this point directly convert pound-force to pound-mass since they are equal at the gravitational constant of 32.2. You can also write it as Kilograms(m)*gravity@9.8m/sec^2(a)=weight in Newtons(F) You can disagree with that all you want but until you can prove Newton's Laws to be false you will be wrong.

Pole Position!

Eddie Vedder ! I was hoping he would leave. Never cared much for their music. I remembered Alec Baldwin had said something similar, but according to snopes.com he never actually said that he would leave. Thanks.

During the 2004 Presidential campaign there was a celebrity who promised to move out of the country if Bush won the election. Does anybody remember who that was? If so, did they move?

Great! Then you could get a job as a White House intern! I don't own a blue dress. It's not my color. Besides, if you ever saw me you would agree that i would make one hell of an ugly woman.

What the OP learned was more a lesson of posting in SC. a) If there is any way possible for a reader to find fault in a posting, they will. b)If a reader finds fault in a posting, they will let you know about it...many times over. c)Not all readers will interpret a post in the same spirit in which it was written. In fact, most won't. d)A poster admitting a mistake will not end debate. e)I was mistaken f)Not all who are wrong will admit it. (slugs*32.2=pounds. Always has, always will.)

If Bill Clinton was ever put up as an example of what a real man is, I would seriously consider a sex change.

What's all the fuss about? Do you really think working for a political appointee doesn't come with certain "understanding? Wake up and open your eyes. And lying about it goes with the territory for the Bush administration. This has been going on for decades, nothing new. Hell, if i were President I would want to make sure any US Attorneys on my watch were of the same political persuasion as I, it's just common sense. When did Bush lie?

I probably should have used that as a title. Good call. Yes, I was wrong in saying pounds are not mass, but your last reply pretty much sums up the whole gist of this thread. There are those who do not know the difference and the article can be very misleading to those people. That was my point.

When I broke my back it was in a racing accident. Also dislocated a shoulder and a knee, plus lots of bruises and a concusion. Lucky for me I was numbed by the trauma so I didn't really hurt until much later. But I'll always remember the track worker who first got to me... "Holy Shit!" Then turns and yells, "He's alive!" My thoughts were, "Wow...musta been a good 'un." "Are you hurting anywhere?" "Huh?" "Ok...don't move. The EMTs are on the way" "Why would I move? I like where I live." "Do you know where you are?" "Huh? Oh...yeah." "Where?" "Uh...uh...hang on, I'll remember in a minute. Where did all these people come from?" The conversation was caught on tape. At the time it wasn't very funny, but years later it's hilarious!

Put a dab of Vics under your nose. It'll cover the smell.
