World Data of COVID-19 (updated)

Here are the World Data of the decease COVID-19, provoked by SARS-COV-2 virus (presented in the image above).

The graph on the left presents the ratio of deaths by country. You need to multiply by 100 to obtain the percentage of deaths.
The global percentage (by now) is 6.22%. 
You can filter the information directly in the data.
And this is the graph with the percentage of death people by country:

3rd place is for United Kingdom

Experiments @Home

In this times of corona virus, we need to stay at home. 
But, that doesn't mean we can't do some experiments.
Here it is a video to perform some experiments at home:

Let's play @home

During this days we can play with our children to try to build something like this:

Or you can create an easy one by using cardboard (image source:

Or like this one (image source:

Let's be creative!

A new era of internet?

Well, not yet. But this is a start to connect quantum computers through a quantum network. Development of experiments to connect two quantum bits is the next step. Let's see what reserves in the future.
"Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature. (...) Currently, the team's focus is on creating the building blocks of a quantum network. Next, they hope to scale up their experiments and actually connect two quantum bits, Faraon says."

A new simplified ventilator for COVID-19 patients

Until now, Italy was the country that was most affected by this SARS-COV-2 virus. But science are trying to fight back. A new simplified ventilator was made to treat patients with respiratory difficulty:

"The 26-strong group of physicists from Europe and North America has designed a new, stripped-down mechanical ventilator that it hopes can be mass-produced quickly and cheaply using off-the-shelf components" in Physics World
Physics can help in every situation. Always.
