Why does a heated can collapse when put in cold water?

In Science Today we did an experiment. We put an empty can over a bunson burner until it was heated and then with tongs quickly put it (inverted) into cold water, it immidietley collapsed! Can you please please explain why?

basically, it can’t handle the pressure change, because cold water is at a higher pressure than normal air, and therefore collapses when submerged into cold water. also the temperature change is unbearable and creates stress in the can

Sales and Marketing Jobs : Industry Overview

Making a career change or new to the industry? Visit http://www.majorplayers.co.uk for the best jobs in the sales and marketing sectors.

Lindsey Myerscough, Major Players Recruiter for Private Sector Marketing Jobs offers an overview to the working within the industry, from salaries to career development opportunities, entry requirements and more.

Not got time for a video? Check out the main points below…

What are the salaries like?
“In the private sector you’re looking at around £18-22k, in the media it’s slightly less as the market is more competitive. A top end salary for a big blue chip organisation could be on the £150-200k+ but on a more average level it’s about £45-55k.”

What about the working environment?
“It’s a very busy environment and you will be expected to do overtime, especially when approaching a deadline for a campaign.”

Can it be stressful/rewarding?
“Deadlines can be stressful and making sure that things are legally above board, but it’s so rewarding seeing your work go live and its impact, for example seeing an outdoor ad or TV campaign that you’ve worked on.”

Do you need a degree?
“It’s good to have a degree in a related subject, so aside from marketing, maybe business studies, but a degree isn’t essential if you have good experience.”

What key skills and personality traits do you need?
“Personality is a big part of being successful within this industry, but of course you do need core skills such as the ability to be diplomatic and be a good strategist.”

How can I get more clued up on the sector?
“Marketing Week, Marketing and Brand Republic are all great. It’s also good to read job descriptions to get an idea of what’s out there and what people are expecting.”

Where could I find USA and Japan statistics?

I’m writing my bachelor job and I’m looking for the most recent statistics in science, technology and innovation levels of USA and Japan. Maybe someone knows where could I find it ?
Thank you.
I mean as Europe has Eurostat , USA should have that sort of thing too, am I right ?

Your requirement is too vague, you need to be more specific and search for something that can be measured. Perhaps number of patents, or number of Nobel awards, or relative number of PC owned.

Online is your best source.

Atheists, here’s a question for you. What if a boulder fell and no one saw it?

You all are in a medieval kingdom and happen to be standing at the bottom of a large and tall cliff. You all are doing this or that when suddenly, a giant boulder falls and roles down the almost vertical cliff from a height and location that nobody can immediately ascertain.

The ruler of the land also happened to witness this, and because he is considering starting a village in this area, he would like to know exactly how this boulder fell.

The purpose of this exercise is to consider how you would go about determining what caused the boulder to fall. You should state how you would determine this, what methodologies you would think prudent in determining this. You should try and determine what specific things you would need to study, and how you would go about organizing them in a way that you can arrive at a more accurate determination of exactly what caused the boulder to fall. You may use whatever knowledge and resources you can possibly drum up to help you in considering the ways you would go about solving this problem.

There is only one rule, you cannot say or try and determine if someone caused it to fall.

Now outside of this hypothetical place, I will tell you how the boulder fell because knowing it is insignificant to the exercise. The you in the hypothetical kingdom world still does not know how it fell. The boulder actually fell because somebody caused it to fall somehow for reasons that are unimportant to the question of how the boulder fell.

And now the only rule you must obey in this, is no matter the evidence, no matter the possibility, no matter the speculation, you absolutely cannot speculate on the presumption that it was caused to fall by anyone. You must find out how it fell absent any intelligence that caused it to fall.

As you’re doing this, I encourage you to speculate on all the possibilities other than someone causing it to fall.

So, how would you determine this?

I know that some of you are already wondering how are you to answer a question that is condemned to be false.

Well this is how modern science works. It does not matter the possibility, the plausibility, or even if it were actually true, science today is conducted on the a most fundamental assumption that God has nothing to do with causing anything.

Now to my purpose in all of this. The whole point of this exercise is to illustrate all of the potential theories and very real plausibilities that can be derived from researching and reading the evidence and other things that could have very well have played a role in causing that boulder to fall. The fact is, you will never know that it was a person who pushed that boulder because you cannot look into the possibility of that actually being the case just like modern science today cannot look into God being a possibility in anything scientists research.

With the boulder that fell, inevitably, a popular consensus will be presumed, perhaps even considered proven as to how the boulder fell, but the truth of how it actually fell will never come to light because that possibility is not allowed to be considered. And in today’s scientific community, not only is it not allowed to be considered, but that consideration and any science done that is indicative of it is shunned and dismissed to remain only as an entry in some scientific journal, and their researcher’s ostracized and removed from their former places of research and learning.

Do you see my point yet? Even if the science pointed to God, the scientist is still forced to take an avenue of research in explaining it that does not point to God. And this, your trust in that science is ultimately why you have decided that God does not exist. I’m not even debating right now whether or not any science we have currently is actually indicative of their being no God, but instead I am illustrating that no matter what, our Science Today cannot possibly be indicative of a God because we always practice it on the fundamental assumption that God has nothing to do with it.

Atheists, here’s a question for you. What if a Creationist wrote a disquisition and no one read it?


What is the job market for english and social studies teachers like?

I am a double major in literature and economics. I am considering law school , but really I want to teach high school. I keep hearing the Job Market is bad for both these types of teachers and it has began making me re-consider my choice of major.

I wouldn’t say the market is "ideal" for social studies teachers, but teachers will always be in demand, especially if you’re a competitive one with a Master’s in Education. Two of my friends were Physics and Biology majors respectively who got their Masters in Education only to receive a ton of offers to teach at different counties. But I have a few friends who majored in the social sciences and got their Master’s, and they still got a few job offers. The minimum requirement is a Bachelor’s, but having that one year Master’s will allow you to secure that one position if you’re hell bent on teaching. Good luck

Technology and innovation – ABB Corporate Research Center in Kraków (Poland)

In 1996 the ABB Executive Board decided to establish a Corporate Research Center in Poland, the first of its kind in Central and Eastern Europe joining ABB Research Organization in Europe, Asia and in the USA.

Krakow, a Southern-Polish city with a traditionally strong academic population, was chosen as the location for Corporate Research Center. Krakow’s 15 universities, 140 Research Institutes and scientific organizations enable 150 000 students to gain high level of expert knowledge and implement it in their work.

ABB Corporate Research Center in Kraków gathers ambitious MSc and PhD scientists who find here excellent working and research conditions. Broad access to emerging technologies makes work in the Center even more attractive.

The international working environment allowing scientists to share knowledge and experience with other ABB colleagues creates unique atmosphere in the office.
