Are Health Expenditure & Life Expectancy Related?

Are Health Expenditure & Life Expectancy Related? | Newnews | Scoop.it

Finally I've decided to blog-out my - still not mature - thoughts on how Something can be created from Nothing. It's all about philosophy and Math, but I'll try to keep it simple, as the most fundamental things in life are simple. Also keep in mind that what follows is not necessarily 'true', but more a 'thought model' helping to explain and to grasp the phenomenon of creating 'something out of nothing'.

'Time Cloaking' remarkable experiment hides event in time

'Time Cloaking' remarkable experiment hides event in time | Newnews | Scoop.it

Researchers successfully created an invisibility cloak from metamaterials. Cornell University physicists have taken this concept, however, to a whole new level – temporal cloaking.

Remarkably, the Cornell scientists managed to basically create a wrinkle in time in which, albeit for a trillionth of a second, any objects that passed through it became invisible and events went unrecorded. Now this is far from being magic, of course, and like spatial cloaking, the time cloak experiment is based on the same principles of physics which discuss the manipulation of light.

Actuary Info Blog: Standard Deviation, a Poor Measure of Risk

Actuary Info Blog: Standard Deviation, a Poor Measure of Risk | Newnews | Scoop.it

One of my favorite statements is that there is no fundamental difference between a religion (believe) or science. Both depend on a number of axioms, the basic assumptions. Assumptions, we 'believe' or 'take for granted' on basis of our intuition and/or personal experience. Only by means of those axioms we're able to 'prove' other theorems in our system or model.


So what we have to conclude is that what we prove in our our statistical models, is as strong as the foundation (assumptions) on which our models are based.

 

Main problem is that the assumptions in our models are so trivial and often so frequently implicitly used, that we don't realize their impact. We've developed a blind spot.......

Construction firm aims at space elevator in 2050 : National : DAILY YOMIURI ONLINE (The Daily Yomiuri)

Construction firm aims at space elevator in 2050 : National : DAILY YOMIURI ONLINE (The Daily Yomiuri) | Newnews | Scoop.it
It may be possible to travel to space in an elevator as early as 2050, a major construction company has announced.

Obayashi Corp., headquartered in Tokyo, on Monday unveiled a project to build a gigantic elevator that would transport passengers to a station 36,000 kilometers above the Earth.

For the envisaged project, the company would utilize carbon nanotubes, which are 20 times stronger than steel, to produce cables for the space elevator.

The idea of space elevators has been described in several science-fiction novels. Obayashi, however, believes it is possible to construct one in the real world thanks to carbon nanotubes, which were invented in the 1990s, the company said.
