question. If you try to hit a baseball thrown at 90 percent of the speed of light、What happens?

("Relativistic Baseball"、Unknown number of pages for e-books)

Ask a funny question like the one above、While the author uses science to have a sense of humor、We will answer with all our might.。
1One answer is quite voluminous.、I thought the author had researched and thought a lot.。

What I personally found interesting were the following themes:。

• "Relativistic Baseball"
• "Spent Nuclear Fuel Pool"
• "Laser Pointer"
• "Making the periodic table of elements in kind"
• "The last artificial light"
• "Half empty cup"
• "Interplanetary Cessna"
• "Yoda"
• "Orbital speed"
• "FedEx Data Transmission Rate"
• "The loneliest person"

For example、In "FedEx Data Transmission Rate"、It says that the transmission speed of the Internet is slower than the speed of the data that FedEx delivers.。

"The data transmission speed of the station wagon, which is piled up with a pile of tape and runs at breakneck speed on the highway,、Don't dream dreams."
—Andrew Tannenbaum
("FedEx Data Transmission Rate"、Unknown number of pages for e-books)

I thought the internet was fast.、This made me feel like scales from my eyes。

Also、In "The Loneliest Person"、It was written about who was the most alone in humanity apart from others.。
Here appeared、The story of an astronaut named Mike Collins of Apollo 11 made me cringe.。
He was the one who remained alone in lunar orbit as a command ship pilot.、In his book, "Carrying Fire: An Astronaut's Journey," he wrote:。

Now I'm alone、I'm Really Alone、And、Completely separated from all known creatures。I am just "it" that has nothing to do with others。If you count the number of people、On the other side of the moon is 3 billion plus 2 people、On this side、Who besides one person、Or God Only Knows What's Going On、be。
("The loneliest person")、Unknown number of pages for e-books)

How alone in outer space、I get anxious just imagining it.。

Another thing that impressed me was the story of otaku.。
In the "Interplanetary Cessna"、About the people who made the X-plane flight simulator、In "Yoda"、I couldn't help but laugh when I read that Star Wars fans publish detailed information about Star Wars on a site called Wookieepedia.。
There are enthusiastic enthusiasts in some field in the world.。
I thought it would be nice to find something I liked so much。
