Hello; I'm carrying 8800 pounds of soil up to my garage roof. It is 12 feet above the ground. I have to make 200 trips with pails of soil and I weigh 200 pounds - so my weight in the equation is an accumulated 40,000 pounds, thus the total weight lifted 12 feet is 48,800 pounds. Let's assume complete efficiency of the calories burned in lifting the weight (unless someone knows a reasonable efficiency percentage for the human body in an activity like this - I'm climbing a ladder). I suppose some consideration should be given to acceleration and deceleration, but l don't think that will significantly alter the end product, so I'm happy to ignore that as well. …

Hi guys. I'm in the process of writing a novel. It is my first book and I'm in my twenties. I'm going to give it a shot because people say I have talent. In my story, the protagonist is under telepathic attack by what I describe as a "paranormal" entity, in the sense that it is beyond the scope of normal human experience and "conventional" scientific understanding, but it is not a demon, I am going to make it an alien. I am thinking about making the entity from another dimension. I want to stay true to m-theory, so I have a question. Are the higher dimensions outside space/time for our dimension, in a way so that a being from one could theoretically move to their dim…

Can one study M.S. in theoretical physics after doing b.tech in environmental engineering? i am pursuing btech in environmental engineering from a reputed college in india. but i have great interest in theoretical physics and want to pursue it from a foreign university. is it possible for me to pursue M.S. in theoretical physics after completing bachelors in environmental engineering?

I've come upon something called general Systems Theory but I don't know weather it is a scientifically mature field, if it has usefull applications already or if it is in an early stage of development. Has anybody read about this? Is it worthy of study? Or just another pseudo science or too-ambitious-to-be-done theory?

I have a question and I'm not sure what subject it would be under? I placed several red potatoes in a bag and vacuum sealed it. 2 weeks later, the bag had puffed up and looked about to explode. Inside, there was quite a bit of liquid and it looked like some of the potatoes had exploded. My questions are: What happened? What was the science going on here? How did liquid get inside a vacuum sealed bag? Was it the potatoes? Why did the liquid come out? HOW did the liquid come out? Why did the potatoes explode??

Hello, I just wanted to know if there is a way to determine the age of an item wood, metal etc without destroying it. Thank you

Is anyone familiar with any data about how many childless single mothers that adopt adopt male vs. how many adopt female children? Also I'd be interested in the same question regarding single childless fathers.

I already knew about non verbal cues forming a greater part of communication amongst people than verbal communication. Body language for business However, I was surprised to find out that shoulder body language is also revealing. For example it can reveal mood, leadership potential, or even the extent to which someone may be telling the truth. This surprised me. Any thoughts? Link

I saw in the tv many occult sciences, like some person walking in air, water? How can it be possible for a magician like chris angel to walk on water?

Hi Everybody Whilst at the beach enjoying the sunset views, a friend of my took a picture of the sunset and showed it to me. Looking at the picture I noticed that there was something that looked like a moon (but much smaller in size) not far from the sun. Surprised, I looked in the direction that the picture was taken but I could not see that moon-like thing so I asked my friend to take another picture. The camera captured the thing again and that's when I realised that the thing was not visible to the necked eye and eversince I have been wondering what that thing is. Is it a star or what? I am interested to know more about this thing. If anyone has a comment, ple…

If mathematics is a language used to formally define and establish the relationship between things with out any ambiguity and if physical models are mathematical models used to model observed reality then why there are so many interpretations of those models? Why do they arise? Does different interpretations mean that the model is incomplete or what does it mean? I am just not able to understand relationship between interpretations, mathematics and physical models.

I had an idea. Could titanium alloy be reinforced with a high tensile strength fiber? Lower melting point titanium alloys: " Ti15Cu15Ni and the newly developed Ti21Ni14Cu. Zr-Ti-rich side of the Zr-Ti-Ni(Cu) alloy system were investigated for brazing of titanium alloys. Low-melting ternary and quaternary eutectic alloys with melting temperatures below 800°C were discovered. Using eutectic as well as off-eutectic braze alloys, CP-Ti and Ti-6Al-4V alloys were successfully brazed at 830°C and 850°C." These alloys show comparable strength to normal high-melting point titanium alloys. "Aluminum nitride is one of the few materials that is both a good thermal cond…

I was wondering how long mankind could survive if we would establish a rule like "You are not allowed to give your child a name that is already been taken". To calculate this I need the number of births each day and the names which are already assigned (or rather the number of words that exist). This is quite easy to get, but the real problem is the measurement of the existing letter combinations which are pronounceable and therefore usable as names. So I need to write a little program that checks all combinations of letters from 2 to "supercalifragilisticexpialidocious" of their pronounceability... But this pronounceability-check depends on rules I don't …

I have formulated the theory on the basis of Carl Jung's theory about personality types. There are four types of personality of people: technician, psychologist, speaker and theorist. These types differ from each other that personality types have different developed functions of a brain. Technician has technical abilities, psychologist has developed intuition, speakerhas developed oral speech, theorist has developed abstract thinking. The share of speakers makes 46 %, technicians – 32 %, psychologists – 20 %, theorists – 2 % in the Ural population.<br style="font-family: Verdana, sans-serif; font-size: 11px; background-color: rgb(230, 235, 236); ">Such politicians a…

With the extreme weather the country has been experiencing, especially over the last year, wireless carriers and the federal government have teamed up and created a new system to automatically warn people of dangerous weather and other emergencies via a special type of text messaging to cell phones. http://www.examiner.com/article/cellphones-to-begin-receiving-severe-weather-alerts-first-nationwide-system

Hi, Just a thought I can't shake, If somehow I managed to balance a Perfect Sphere on a pin head & then perfectly spin the sphere, I'm thinking the sphere would spin for a very, very long time. Any feedback would be great, Thanks

I know that over time the concept of IQ has proven to be flawed but it is still popular on television and it has made me intrigued about the highest results ever achieved... Maybe I could profundize on their biographies... I already saw that the person with the highest IQ ever measured achieved great things but not as great as people that have not had their IQ measured... Any psychologist out there knows the 5, 10 or 50 highest results ever and who got them and how high these were? and at which age which they were measured?

What if in the new age of this world, knowledge wasn't just something thats stored in books, CDs and databases etc. Physics, chemistry, mathematics, biology, computer science....! What if this knowledge was a contained in a hyper meta state and then passed on to rather distributed thru brain membrane. So people would never then call a so called singular person a genius or more literate of his membranous tissue brain thriving knowledge but the brain infact stored volumetric contained knowledge in the medium surrounding it. Then the students, practitioners etc did not earned in rational test questions but had that meta state knowledge access. So whoever would had the means …

I woke up yesterday and found all this black material under my testicles. what is this. is it an std? as soon as i scrape it off it returns hours later! help

"Buying a piezoelectric transducer can be quite expensive. Two different suppliers I looked at were Face International Corp. and Active Control eXperts. Their piezo-transducers sold for about $100 and $200 respectively. Buying piezoelectric cable is much cheaper. One supplier in the UK, Ormal Electronics Ltd., gave a quote of £2.75 per meter for purchases of more than 2000 meters. Another supplier in the US, Measurement Specialties Inc., sells piezo-cable for $8.00/m for more than 1000 m." http://www.linkedin.com/answers/Sustainability/green-products/SUS_PRD/444508-22603425 Piezoelectric materials like Quartz is a pretty common substance, …

Why aren't girls into pornography? i.e. as much as most guys are. Anybody know?

Perhaps the atomic bombs on hiroshima and nagasaki were not dropped by american jets but were fallen from alien sky portals!? So much of the world has changed after world war 2? Are we living in a developing world or a rehabilitation world?

In the movie 'alien' it seems the beginning of the movie is a real science expedition! The cosmonaut suit and helmet head gear is just like the russian cccp space programs! So the abandoned ship they study, the huge caracass of alien sitting on a telescope, the alien eggs...etc is it real somewhere? Does the nasa colombia space shuttle and mir space stations dock at a specific flight path in the space, and then the cosmonaut enter the shell cabin going into a portal sleep where they wake to the alien world planet??? If this were true, then how come the alien planet abandoned space station already had human settlements, computers programs interface and life sustain…

Hey all! I am writing a 10 page research paper on technological singularity and presenting the topic with a 12 minute presentation. I was hoping to get some of your ideas on technological singularity so I can expand on my own ideas already (one of the areas I am covering is ethical questions involved with artificial/above human intelligence) So please comment your view point!
