    Humidity and perceived temperature

    OK, I just got back from Colorado, and so in the last six months I've been there both in wintertime and summertime. In the winter, it seems about ten degrees warmer than it does in Texas at the same temperature because the air is so dry. In summer, it seems about ten degrees cooler than in...

    Evolution of Venus Temperature & Climate

    It is often claimed that Venus surface temperature as high as 450 - 500 degrees Celsius suggests a carbon dioxide greenhouse effect (around 96.5% of its atmosphere consists of CO2). However, if one deals with the question in an unprejudiced, honest way, then the hypothesis of such a greenhouse...

    A few questions about WTC Debris/ Ground Zero

    Hey, I'm a first time poster on JREF, and NOT a truther. I have a few quick questions, which I've searched for but, for whatever reason, cannot find. 1.People like Peter Tully, Mark Louiseaux, and other rescue/cleaning crew report molten steel. -Are any of these people qualified to determine...

    Z-pinch Sunspots

    On the z-pinch and sunspots as examples of z-pinch phenomena. In other threads much of the electric sun model has been discussed at some lenth and confusion of subject matter. A certain poster has made two claims in seperate threads, one that sunspots are where Birkeland currents enter the sun...

    Thermal radiation, temperature and energy

    One for a patient physicist - coming from an electronics background I basically understand the emission of EM radiation/photons by oscillating charges, electron transition through a bandgap, nuclear decay and spontaneous emission, but can't seem to recall a conceptual mechanism for thermal, or...

    The real cause of black smoke?

    WTC fires, thick black smoke. Claimed by troofers to indicate low temperature and lack of oxygen. http://www.infowars.com/images2/world/madrid_%20wtc_fires.jpg (Image linked from infowars.com without permission. @#$% you, Alex Jones. :p ) Buncefield Oil Terminal Fire, December 11, 2005.

    Molds and molten metal...

    Hello everybody, I know the answer must be simple, but I've been thinking about this problem for days and haven't been able to find a good answer. I understand that molten metal is poured into containers made of materials that have a melting point superior to that of the metal. To create...

    Temperature Measurement

    Is it possible to develop a entirely new method of measuring temperature that starts at absolute zero, and isn't really built around the freezing point or boiling point of something, but instead is based purely on average kinetic (heat) levels? Ideally something linear (20 units would be 10...

    Direct vs. indirect measurements - for AgingYoung and others

    This is split from the "Danny Klein - Fuel from Water" thread. A long discussion started when, in response to a comment that the Sun's temperature could not be measured, followed by a comment that it certainly could, AgingYoung said A number of other comments followed, like and A...

    Normal Body Temperature?

    From a contribution from reader and professor of physics at Lakehead University, Canada, William Sears in this week's commentary I have always taken normal body temperature in Celcius to be 36.8. Perhaps this has been a forwards conversion from 37 Celsius to 98.6 Fahrenheit and then backwards...

    Temperature of distilling water

    This is the initial spark that started my rant (see 'Science is...). The students had an exam. In this exam, there was a question which showed a distillation set-up with a burner, a tripod, a round-bottomed flask with impure water in it, a thermometer inserted in the very top of the flask (not...

    A Question on Light and Temperature

    Greetings I was told this today: When light approaches the coldest temperature, which is not zero degress but negative 273 degrees celsius or negative 459 degress fahrenheit (termed "absolute zero"), it ceases to move. Nothing can ever be colder than absolute zero since it is the point at...

    Cell phone and ear temperature

    Ok, so cell phones still do not cause cancer. However a small survey of mine indicates that everyone experiences excessive sweating and a sensation of heat in the ear when talking for a long time. I tried Googling for the cause of this, but came up with nothing except warnings about cell...
