Urban legend: The billion dollar pen

There is a joke that keeps on making the rounds, about how NASA discovered that normal pen does not work in space, and then spent a huge amount of money in research and developing a pen that works in space; and what did the Russians do ? Well, they did not waste money like this, and instead used a normal pencil.
Well, as the linked article (link) shows, this is an urban legend with no basis in truth. Read the complete article to find out:

The story goes like this: in the 1960s, NASA astronauts discovered that their pens did not work in zero gravity. So like good engineers, they went to work and designed a wonder pen. It worked upside down. It worked in vacuum. It worked in zero gravity. It even worked underwater! And it only cost a million dollars! The crafty Russians used a pencil.
This story, like most modern urban legends, has proliferated on the Internet, but it has also been passed by word of mouth. I’ve even heard a well-known space historian tell the story while talking about his new book, getting the expected laugh from his audience when he held up a Number 2 pencil for the punchline. And, of course, the story has also been embellished, with the cost of the writing device getting ever higher, from a million dollars to a hundred million dollars to a billion dollars in some variations. Undoubtedly at some point the cost will equal the mythical trillion-dollar price of a mission to Mars.

Theory: Is the universe really existant, or is it a hologram

Science delves on cold facts, theories, experiments, and explanations that cover all these. But sometimes, there are theories that are difficult to accept, although there are experiments that are equally difficult to understand. What do you make of an experiment that proves that under certain conditions, particles such as electrons are able to communicate with each other even though they are far away from each other; so, even though Einstein's theory says that nothing can move faster than the speed of light, this experiment seems to suggest that particles can communicate with each other instantly, much faster than light. One theory takes from this approach, and suggests that the universe in fact is just a hologram (link to site):

University of London physicist David Bohm, for example, believes Aspect's findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram.
To understand why Bohm makes this startling assertion, one must first understand a little about holograms. A hologram is a three- dimensional photograph made with the aid of a laser. To make a hologram, the object to be photographed is first bathed in the light of a laser beam. Then a second laser beam is bounced off the reflected light of the first and the resulting interference pattern (the area where the two laser beams commingle) is captured on film. When the film is developed, it looks like a meaningless swirl of light and dark lines. But as soon as the developed film is illuminated by another laser beam, a three-dimensional image of the original object appears.

Book: Forward the Foundation by Isaac Asimov (1993)

Isaac Asimov wrote a huge amount of science fiction over the years, and is known for many of his books such as the Empire Series, and most famously for the Foundation Series. The 3 main Foundation books were the 'Foundation', 'Foundation and Empire', and 'Second Foundation'. It was later, in order to try and fill more details, that Asimov wrote more books for the Foundation, that include books that were both prequels and sequels. The last such book that he wrote was called 'Forward the Foundation', and was released in 1993, a year after Asimov died. Forward the Foundation was a sequel to 'Prelude to Foundation', carrying on with the story of Seldon's search for how to develop the story of psycho-history.

Book: Pale Blue Dot by Carl Sagan (1994)

The complete name of the book is called "Pale Blue Dot: A Vision of the Human Future in Space" and it was another non-fiction book released by Carl Sagan (the famous astronomer and scientist) who wrote a series of books on science and space, and is most famous for his works, Cosmos and Contact. The name of the book is based on a photograph taken by the space explorer spacecraft, Voyager 1. Carl Sagan had pushed for the spacecraft to take a photograph when it was at a huge distance from the earth, a distance of 3.7 billion miles. In this photograph, the Earth seems nothing more than a Pale Blue Dot in the midst of empty space, and this is all that mankind has got.
Carl Sagan also described this photo in a speech he was giving, with these starting words: "Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam."



The book takes a look at previous theories of the geocentric Earth-centered universe, and how that was the idea that could not be challenged, with torture awaiting those who dissented. Slowly, that idea was overturned and we started learning about reality, about our true size in the enormity of the universe, starting with the scale of the solar system, and then continuing with the idea of how to explore the planets in the solar system. Carl Sagan also talks in detail about the Voyager program. The book also has some great photos of the Solar System, courtesy of NASA.

Contact, a science fiction book by Carl Sagan (1985)

Contact is famous as a science movie starring Jodie Foster, released in 1997. The movie was a great science fiction movie, earning more than $140 million worldwide, and won a Hugo Award. The movie was based on the novel by the same name, published in 1985. In fact, Carl Sagan had been working on a story for a film on the theme of Contact ever since 1979 along with his wife Ann Druyan, and had been working on the idea with Warner Bros., but the movie never got made in that timeline, and hence Carl Sagan started working on a book on the same idea, and released the book in 1985. Years after the book, the idea for a movie was again taken up, and after a change of directors and script-writers, the movie was finally released in 1997. There are differences between the book and the movie, with the number of travelers being different, the detail of the machine (the machine had to be detailed much more thoroughly in the movie version), as well as whether there is hope in the end.



The book takes up the story of contact from extra-terrestrials, but this is not the Independence Day or Encounters of the Third Kind kind of contact, this is more about the kind of contacts that scientists think will happen; through the twin model of mathematics (the only universal language in which people can communicate through), and through radio waves from outer space, which is what scientists are looking for through the SETI and other similar programs.
The book is about Eleanor "Ellie" Arroway, who is the director of "Project Argus," a project in a large number of radio telescopes in New Mexico have been dedicated to the search for extraterrestrial intelligence (SETI). Then suddenly, one day, they receive a signal that seems to confirm that there are indeed other intelligence sources in the galaxy. The signals contain a blueprint for building an advanced machine without disclosing what the machine will do. The design are in excess of current capabilities and require a huge effort.
Eventually, the machine is built, and it takes 5 passengers to the center of the Milky Way through a number of wormholes, where the passengers seemingly meet people who were part of their life such as close relatives (these are in fact the senders of the message who have taken this form). However, when the travelers return to earth, the journey of many hours seems to have been done in 20 minutes, video footage has been burned out, and they are faced with a skeptical Government machinery, suspected of fraud. The one possible ray of hope is mathematics, with a message encoded inside the further section of Pi.

Cosmos by Carl Sagan (1980): Great book about science

Carl Sagan (Wikipedia) died in 1996 of cancer, dying relatively young at the age of 62. Carl Sagan was one of the people who did a huge amount to popularize the concept of science, especially related to space travel. His most popular work to date remains Cosmos, which was also made into an incredible 13 part TV series in 1980 (Cosmos: A Personal Voyage), that has so far been seen by 600 million people (including a large number of children). I remember being fascinated by the series when it used to come on TV when I was a child; there is a certain fascination of the heavens that draws people to it, especially children. The series should be made essential watching for school going children all over.



The book is based on the series, and is considered a companion to the TV series. It is one the best-selling books in the area of science, while typically science books do not sell as well. The book is divided into 13 chapters, and follows the TV series to a large extent, but there are certain variations (typically when Carl Sagan has already written about something in an earlier book, and it is explained in detail in the TV series). The various chapters are:

Introduction
1. The Shores of the Cosmic Ocean
2. One Voice in the Cosmic Fugue
3. The Harmony of Worlds
4. Heaven and Hell
5. Blues for a Red Planet
6. Travelers' Tales
7. The Backbone of Night
8. Travels in Space and Time
9. The Lives of the Stars
10. The Edge of Forever
11. The Persistence of Memory

Why did you stop stirring ?

The US finally sent the first manned space mission to Mars. The spacecraft gently touched down and the astronaut descended and tested the atmosphere. Low and behold it was safe for people to breathe. He removed his space suit and exited the spacecraft.
He was amazed to find himself in a lush green valley surrounded with beautiful wooded hills. He hiked for some distance and came upon a beautiful little white cottage with a lush green lawn surrounded by a white picket fence like something out of "Better Homes and Gardens." He walked up to the front door and found it open.
He walked inside, looked around and hearing noises from the kitchen he went back there. WOW, to his amazement he saw the most beautiful blonde he had ever seen standing over a large pot on the stove. Inside the pot was a gooey mess that she was stirring with a large spoon. As he watched she kept stirring and stirring.
After a couple hours he finally asked her what she was doing. She replied that she was having a baby. He was quite skeptical but after a couple more hours of stirring
she reached down into the gooey mess and pulled out a beautiful baby girl. He told her that was really amazing but that was not the way it was done on Earth. She replied " How do you do it on Earth ?"
With a twinkle in his eyes he said, "Come on back to the bedroom and I'll show you." After an hour of the wildest sex he had ever experienced he lay back exhausted and
lit up a cigarette. She said " Well where is the baby?"
He said " Oh that takes nine months."
She replied, "Well why did you stop stirring?"
