The Black World Of Solitude.

Hello.

Let me share another interesting discovery with all of you people.

This may be known by some people, but I'm just posting it.

Ok, I shall crap no further.

The power of vacuum. From the title we can tell that this discovery has something to do with vacuum. Basically, vacuum is a region of space with nothing in it, not even air. Which means a perfect vacuum has no pressure at all, but it is hard to create a perfect vacuum on Earth even with advancements in technology.

Next, water boils at a lower temperature when its surroundings have a lower pressure than the pressure at sea level.

So if you mix these two ideas pieces of information, then you will realise... ...

Water boils in a vacuum at room temperature! (Or perhaps a temperature higher than room temperature but lower than 100deg Celsius)

So there you have it, a water boiling system that requires no heat!

Furthermore, boiling is an endothermic process (a process that takes away heat), therefore after a while the remaining water left that did not boil will turn to ice (or cold water)!

So there you have it, a water boiling system which requires no heat and an ice making system which requires no freezer!

Ok, CHANGE OF TOPIC.

On the first page of Yahoo! Singapore, what do you see near the bottom of the screen without scrolling the page down?

"WHO declares H1N1 flu a pandemic"

Oh no.

Let me just copy the article, not to worry, i will put in the credits.

By MARIA CHENG and FRANK JORDANS,Associated Press Writers AP - Friday, June 12 GENEVA - Swine flu is now formally a pandemic, a declaration by U.N. health officials that will speed vaccine production and spur government spending to combat the first global flu epidemic in 41 years.

Thursday's announcement by the World Health Organization doesn't mean the virus is any more lethal _ only that its spread is considered unstoppable.

The U.S. government has already increased the availability of flu-fighting medicines and authorized $1 billion for developing a new swine flu vaccine. In addition, new cases seem to be declining in many parts of the country, U.S. health officials say, as North America moves out of its traditional winter flu season.

Still, New York City reported three more swine flu deaths Thursday, including a child under 2, a teenager and a person in their 30s.

"Countries where outbreaks appear to have peaked should prepare for a second wave of infection," Chan warned.

-From Yahoo! Singapore News.

Ok, I cut the article short. You could check it out yourself.

Anyways, the last paragraph of the abstract is the last paragraph of the real article.

But it is the last paragraph that made me panic.

"Second wave of infection"

I went to check the previous flu pandemics that happened last time. Those that happened in the 1900s were the Spanish Flu (1918-1919, subtype H1N1), the Asian flu (1957-1958, subtype H2N2), and the Hong Kong Flu (1968-1969, subtype H3N2).

All these three flu pandemics had a second wave of infection. The second wave was more deadly for the Asian flu and the Hong Kong flu. The second wave of the Spanish Flu was believed to cause a cytokine storm in human beings, therefore killing so many young and healthy adults. By the way a cytokine storm is the overreaction of your immune system, so it can kill you.

The second wave of influenza pandemics usually take place in the later months of the year. Therefore, we may be moving towards the second wave of the pandemic, one that may cause many deaths. However, there is nothing we can do right now but to pray hard that the second wave will not be extremely deadly.
