We will we remember Stephen Hawking

Last month, March, he passed away. He was 76.

His name will be remembered for some time.

He was not always right, but his writing got the attention of a large number of people. While in a wheel chair and unable to speak he gave  lectures at Cambridge. And he wrote books with the help of others.

How will we remember Stephen Hawking?

First, and many times with collaborators, for his seminal work on black holes, entropy and the radiation emitted from the black holes. Second, for his copious and popular writings of both nonfiction and fiction, making physics more interesting and understandable to the general public. Third, his heated and unsuccessful arguments with other physicists that the Higgs boson, if it existed, could never be found. (Incidentally, he was proved wrong in 2012.)

The paragraph above has some links you can follow for more information. His books are available on-line at Amazon.


An Unusual Number Of Natural Disasters.

Even Skeptics Say it. More Global Disasters.

Proof of Climate change? Look at the facts yourself.

Forbes magazine is one of many now saying there are more disasters from natural causes.l Here is a short list of thi9ngs that are called ‘natural’ instead of man-made

  1. Earthquakes.
  2. Hurricanes.
  3. Wild Fires. (When not caused by humans.)
  4. Tsunamis.   (Tidal Waves.)
  5. Mus slides. (Southern California.)
  6. Floods. (Other that failures of damns and levees.)
  7. Animal attacks. (Almost 2,000 people die each year for  form animal attacks.)
  8. Disease epidemics when no cause by human behavior.

The list above is not recompile and is may not represent the order of severity. One could asrgure about how much of these things really are due to so9mething that humans have done. Consider theincrease is human population.

This chart shows the the rate of growth ans slowed down. But we are still growing. Look back about 200years ago and see that  we were about one billion people on this planet. Now we are around 8 billion.

Now then, here are  some factoids from the Forbes magazine article publish bank in October of last

Mexico is especially prone to earthquakes because they’re surrounded by fault lines, in a subduction zone (the Cocos slab submerges under the North American plate). Vox has a good piece they published yesterday (Sept 20, 2017) recapping the earthquakes in Mexico,…

The article above also said:

It is premature to conclude that human activities–and particularly greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global tropical cyclone activity. That said, human activities may have already caused changes that are not yet detectable due to the small magnitude of the changes or observational limitations, or are not yet confidently modeled (e.g., aerosol effects on regional climate).

What do you thing? How can are presence here not have some large impact on nature?

Now then, after saying that, please think about this. History does record t there have been some very bad things that have taken place on the earth. But often very few people were hurt because there were very few people liking in the area.  An area  in China that had a huge earthquake also had a history of a a huge earthquake a lo0ng time ago. But there were few human deaths back then. Other examples can be given of historical events that did not kill a lot of people.

But it is known for sure that human used of a chemical did make a hole in the upper stratosphere. So that  chemical compound was banned and it helped. Read the item below:

So does Human activity has some impart on the environment. Yers indeed!
