MindReader and learning
The specialists of the International center for education "Areopagit" (www.areopagit.com) develop the "convincing" to learn program. This program is designed on the base of the research of Dr. Igor Smirnov “Semantic Stimuli Response Measurements Technology”, or SSRM Tek, a software-based mind reader that supposedly tests a subject's involuntary response to subliminal messages.
The program inspires to recipient an idea about need to learn, think and develop their own abilities. If to unite this program with a network self spreading module (like a virus) then during several months it would install on hundreds of thousands of personal computers around the world. Besides, program can define the language of the user and use suitable - an English, French, Chinese, Spanish, German, Russian or Arabic.

Creativity in science
Does anybody know any course in creativity in science? I'm interested in this theme.

How do you calculate lost work for a condenser or a boiler if the surrounding temperature isn't given? And you don't know how the condenser or boiler operates. You're given entropy and enthalpy for all entrance and exit streams and the heat applied/lost to the surroundings.

Does anyone know of any software that can perform McCabe-Thiele method for separation processes? My professor requires us to hand our last exam online and it would be very tedious and crude to do the method in Excel or maybe Photoshop, Paint, etc. I could do with paper and pencil but I have no scanner near me. Help!

I need to start looking for a co-op once more, so I was wondering what experienced people have had. This ranges from looking for co-ops, interviews, and actually being on co-op. In my school it's common (or at least somewhat encouraged) for Cheme's to leave for a year, rather than a semester because all the courses are only offered once a year (and are prereques for one another). Is it (was it?) like that in in your case(s)?
Additionally, if any of you college grads are working someone and can mention a co-op opportunity for a Junior-year cheme, it would certainly be appreciated. Location isn't really an issue, and I can't imagine someone recommending where they're working if they're miserable there.
Also, I think three entries back in my own journal I wrote something (I hope) many of you will find rather amusing. I suppose some people *might* be uncomfortable reading it... maybe... but I wouldn't go so far as to say it's not safe for work any more than a dirty joke might be. Here's a link
. It's a public entry, and I submitted the assignment for the professor, so really, how bad could it be?

I was wondering what kind of internships you guys are currently involved in or have done? Right now, I'm trying to apply for a Brookhaven Lab internship and maybe get into their material science department XD Are there any other beneficial internships that you guys could recommend?

TOP 20 ENGINEERS' TERMINOLOGIES
1. A NUMBER OF DIFFERENT APPROACHES ARE BEING TRIED - We are still pissing
in the wind.
2. EXTENSIVE REPORT IS BEING PREPARED ON A FRESH APPROACH TO THE PROBLEM -
We just hired three kids fresh out of college.
3. CLOSE PROJECT COORDINATION - We know who to blame.
4. MAJOR TECHNOLOGICAL BREAKTHROUGH - It works OK, but looks very hi-tech.
5. CUSTOMER SATISFACTION IS DELIVERED ASSURED - We are so far behind
schedule the customer is happy to get it delivered.
6. PRELIMINARY OPERATIONAL TESTS WERE INCONCLUSIVE - The darn thing blew up
when we threw the switch.
7. TEST RESULTS WERE EXTREMELY GRATIFYING - We are so surprised that the
stupid thing works.
8. THE ENTIRE CONCEPT WILL HAVE TO BE ABANDONED - The only person who
understood the thing quit.
9. IT IS IN THE PROCESS - It is so wrapped up in red tape that the situation
is about hopeless.
10. WE WILL LOOK INTO IT - Forget it! We have enough problems for now.
11. PLEASE NOTE AND INITIAL - Let's spread the responsibility for the screw
12. GIVE US THE BENEFIT OF YOUR THINKING - We'll listen to what you have to
say as long as it doesn't interfere with what we've already done.
13. GIVE US YOUR INTERPRETATION - I can't wait to hear this bull!
14. SEE ME or LET'S DISCUSS - Come into my office, I'm lonely.
15. ALL NEW - Parts not interchangeable with the previous design.
16. RUGGED - Too damn heavy to lift!
17. LIGHTWEIGHT - Lighter than RUGGED.
18. YEARS OF DEVELOPMENT - One finally worked.
19. ENERGY SAVING - Achieved when the power switch is off.
20. LOW MAINTENANCE - Impossible to fix if broken.

For Chemical Engineers Only
I found something amazing in her
Like that special thing in polymers
Unique but spontaneous
Covalently bonded yet flexible
She's easy to understand
Unlike the IUPAC Method
No need for partial derivatives
Nor tedious Fourier and Laplace
You need no thermodynamics
To describe her changing state
Only a little understanding of kinetics
To predict how fast are her rates
She's more than a transfer function
Far important than unit operations
Her dynamics are not represented by equations
Yet she's as simple as your ordinary addition.
However life is a distillation column,
With no reflux and delta points
I'm the bottoms and she's the condensate
And it is in our nature to separate.
== I saw this posted outside our department, posted by Prof Bajamundi. I don't know if he composed it or downloaded somewhere.

Have you ever had, in your previous ChE courses, a requirement in which you are to submit a design proposal regarding practical usage of fuels? It's not some plant design requirement for graduation but just a little feasibility/ comparison thing. This subject is just intro to chem engg.
Examples are like, which is more economical: propane or methane as fuel for heat exchangers. Or a proposal for ammonia as a substitute fuel. Something like that that encompasses topics on fuels and mass and energy balances. We are to present our proposal as a final project for the course. Can anyone help? The deadline is nearing and I still don't have a topic in mind.
Garr. I'm bad at these things. A reason why I never went to Chem. Why not just give me the problem and I'll solve it.

Thermodynamics of Hell
The following is one of Dr. Schalmbaugh's Final Test questions for May 1997. (Dr. Schalmbaugh, University of Oklahoma School of Chemical Engineering is known for asking questions such as this on his final exams.)
May 1997, Momentum, Heat and Mass Transfer II Final Exam Question:
"Is hell exothermic or endothermic? Support your answer with truth.''
Most of the students wrote proofs of their beliefs using Boyle's Law or some variant. One student, however, wrote the following:
"First, we postulate that if souls exist, then they must have some mass. If they do, then a mole of souls can also have a mass. So, at what rate are souls moving into hell and at what rate are souls leaving?
I think that we can safely assume that once a soul gets to hell, it will not leave. Therefore, no souls are leaving. As for souls entering hell, lets look at the different religions that exist in the world today. Some of these religions state that if you are not a member of their religion, you will go to hell. Since there are more than one of these religions and people do not belong to more than one religion, we can project that all people and all souls go to hell.
With birth and death rates as they are, we can expect the number of souls in hell to increase exponentially.
Now, we look at the rate of change in volume in hell. Boyle's Law states that in order for the temperature and pressure in hell to stay the same, the ratio of the mass of souls and volume needs to stay constant.
Case 1: If hell is expanding at a slower rate than the rate at which souls enter hell, then the temperature and pressure in hell will increase until all hell breaks loose.
Case 2: If hell is expanding at a rate faster than the increase of souls in hell, then the temperature and pressure will drop until hell freezes over.
So which is it? If we accept the postulate given to me by Theresa Banyan during my freshman year, "it will be a cold night in hell before I sleep with you" and take into account the fact that I still have NOT succeeded in having sexual relations with her, then case 2 cannot be true.
Thus, hell is exothermic."
The student, Tim Graham, got the only A. Current Mood: cynical

Hello. I'm not sure if I've posted here before; I'm in my third year of chemE, studying in Ecuador. We were sent to write a paper in Thermo on various topics (just something brief on each of them), and one is to write about why is the second law of thermodinamics valuable in this career? I've read about the second law, but I'd like to have other opinions on why it's so importante. Thanks.

well...it's that time of year again...and I am on a search for books cheaper than the campus store
TITLE: TRANSPORT PROCESSES & SEPARATION PROCESS PRINCIPLE
4th edition, CP 2003
Anyone got it?
