HEAVEN IS HOTTER THAN HELL ??

HEAVEN IS HOTTER THAN HELL ??

The temperature of Heaven can be rather accurately computed. Christian authority is Isaiah 30:26, "Moreover, the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days." Thus Heaven receives from the Moon as much radiation as we do from the Sun, and in addition 7*7 (49) times as much as the Earth does from the Sun, or 50 times in all.

The light we receive from the Moon is one 1/10,000 of the light we receive from the Sun, so we can ignore that ... The radiation falling on Heaven will heat it to the point where the heat lost by radiation is just equal to the heat received by radiation, i.e., Heaven loses 50 times as much heat as the Earth by radiation. Using the Stefan-Boltzmann law for radiation, (H/E)^4 = 50, where E is the absolute temperature of the earth (300K), gives H as 798K (525C). The exact temperature of Hell cannot be computed ...

[However] Revelations 21:8 says "But the fearful, and unbelieving ... shall have their part in the lake which burneth with fire and brimstone." A lake of molten brimstone means that its temperature must be at or below the boiling point, 444.6C. We have, then, that Heaven, at 525C is hotter than Hell at 445C.

Einstein vs Newton [A bit of Joke in the morning]

Once all the scientists die and go to heaven. They decide to play hide-n-seek. Unfortunately Einstein is the one who has the den. He is supposed to count 
upto 100 and then start searching. Everyone starts hiding except Newton. 
Newton just draws a square of 1 meter and stands in it, right in front of
Einstein.
Einsteins counting ....97,98,99,100, opens his eyes and finds Newton
standing in front. Einstein says "Newtons out, Newton's out."

Newton denies and says I am not out. He claims that he is not Newton. All
the scientists come out and he proves that he is not Newton. how?

Newton says:
I am standing in a square of area 1m square.. 
That means I am Newton per meter square.. 
Hence I am Pascal.

Since newton per meter square = Pascal

--------------------------------------

If you didn't get the joke, you probably didn't understand the science behind it. If this is the case, it's a chance for you to learn a little physics.

Promoting TEchnology Use in School

Although there has been a strong push to get educational technology into the hands of teachers and students, many obstacles to implementation still exist. Equipment may not be placed in easily accessible locations. Hardware and software often pose problems for teachers in the classroom, and just-in-time technical support may be unavailable. Teachers may lack the time and the motivation to learn technology skills. Professional development activities may not provide ongoing, hands-on training for teachers or practical strategies for implementing technology into lesson plans. Initial technology funding may not be sustained and thus not capable of providing upgrades, maintenance, and ongoing professional development. Fortunately, these obstacles can be addressed and overcome. This Critical Issue provides practical information for promoting technology use in schools.

The push to provide technology in schools has been successful in recent years. According to Ministry of Education, most schools have computer labs and many have computers in every classroom. More than 90 percent of all schools are connected to the Internet, and more than 33 percent of teachers have Internet access in their classrooms. Yet teachers readily admit that they are not making as much use of technology as they could. According to an Education survey, nearly 30 percent of teachers said their students use computers only one hour per week; nearly 40 percent said their students do not use computers in the classroom at all. Although technology is more prevalent in the schools, several factors affect whether and how it is used. Those factors include placement of computers for equitable access, technical support, effective goals for technology use, new roles for teachers, time for ongoing professional development, appropriate coaching of teachers at different skill levels, teacher incentives for use, availability of educational software, and sustained funding for technology.
