25th May 1961 – Kennedy’s Moon Speech

25 May 2009

On May 25, 1961, President John F. Kennedy announced before a special joint session of Congress the dramatic and ambitious goal of sending an American safely to the Moon before the end of the decade. A number of political factors affected Kennedy’s decision and the timing of it. In general, Kennedy felt great pressure to have the United States “catch up to and overtake” the Soviet Union in the “space race.” Four years after the Sputnik shock of 1957, the cosmonaut Yuri Gagarin had become the first human in space on April 12, 1961, greatly embarrassing the U.S. While Alan Shepard became the first American in space on May 5, he only flew on a short suborbital flight instead of orbiting the Earth, as Gagarin had done. In addition, the Bay of Pigs fiasco in mid-April put unquantifiable pressure on Kennedy. He wanted to announce a program that the U.S. had a strong chance at achieving before the Soviet Union. After consulting with Vice President Johnson, NASA Administrator James Webb, and other officials, he concluded that landing an American on the Moon would be a very challenging technological feat, but an area of space exploration in which the U.S. actually had a potential lead. Thus the cold war is the primary contextual lens through which many historians now view Kennedy’s speech.

The above clip is from NASA’s page on President Kennedy’s announcement of the decision to go to the Moon.

Here is an audio recording of the speach I found on YouTube.

Twelve people have walked on the surface of the Moon.

Apollo 11

  • Neil Armstrong – Commander
  • Edwin E. Aldrin, Jr. – Lunar Module Pilot

Apollo 12

  • Charles Conrad, Jr – commander
  • Alan L. Bean – lunar module pilot

Apollo 14

  • Alan B. Shepard, Jr – Commander
  • Edgar D. Mitchell – Lunar Module Pilot

Apollo 15

  • David R. Scott – Commander
  • James B. Irwin – Lunar Module Pilot

Apollo 16

  • John W. Young – Commander
  • Charles M. Duke Jr. – Lunar Module Pilot

Apollo 17

  • Eugene A. Cernan – Commander
  • Harrison H. Schmitt – Lunar Module Pilot

Apollo 17 left the surface of the Moon on 14th December 1972. We have not been back since then.


Swine Flu, Knowledge Enables Prevention

29 April 2009

Thunderf00t’s YouTube Video on the recent outbreak of swine flu.

And this is Thnderf00t’s comment to the video.

How can I protect myself from getting swine influenza from infected people?

In the past, human infection with swine influenza was generally mild but is known to have caused severe illness such as pneumonia For the current outbreaks in the United States and Mexico however, the clinical pictures have been different. None of the confirmed cases in the United States have had the severe form of the disease and the patients recovered from illness without requiring medical care. In Mexico, some patients reportedly had the severe form of the disease.

To protect yourself, practice general preventive measures for influenza:

•Avoid close contact with people who appear unwell and who have fever and cough.

•Wash your hands with soap and water frequently and thoroughly.

•Practice good health habits including adequate sleep, eating nutritious food, and keeping physically active.

If there is an ill person at home:

•Try to provide the ill person a separate section in the house. If this is not possible, keep the patient at least 1 meter in distance from others.

•Cover mouth and nose when caring for the ill person. Masks can be bought commercially or made using the readily available materials as long as they are disposed of or cleaned properly.

•Wash your hands with soap and water thoroughly after each contact with the ill person.

•Try to improve the air flow in the area where the ill person stays. Use doors and windows to take advantage of breezes.

•Keep the environment clean with readily available household cleaning agents.

If you are living in a country where swine influenza has caused disease in humans, follow additional advice from national and local health authorities.

19th April 2009 – J. G. Ballard

19 April 2009

The following is taken from this article in The Guardian.

JG Ballard, novelist and short-story writer, has died after a long battle will illness, his agent has said.

The 78-year-old author, who was best known for the award-winning Empire of the Sun, a semi-autobiographical novel written in 1984, and his controversial novel, Crash, later adapted into film by David Cronenberg.

His agent, Margaret Hanbury, said it was “with great sadness” that Ballard had passed away this morning after several years of ill health.

Member of the New Wave of science fiction authors,  JG Ballard was one of the first science fiuction authors I read in the sixties. I remember reading The Drowned World, The Crystal World and The Terminal Beach (which I still have in my library). Not my favorite science fiction author – too “psychological” for my taste – I was in to hard science fiction.


How to grow your own fresh air (TED)

15 April 2009

Researcher Kamal Meattle shows how an arrangement of three common houseplants, used in specific spots in a home or office building, can result in measurably cleaner indoor air.

How strange. I have at one time or another in the past owned all three of the plants mentioned. They all died of neglect. Maybe I should try again…


Remembering Apollo

9 April 2009

The flight computer onboard the Lunar Excursion Module, which landed on the Moon during the Apollo program, had a whopping 4 kilobytes of RAM and a 74 KB “hard drive.” In places, the craft’s outer skin was as thin as two sheets of aluminum foil.

This quote is from an article at Physorg.com titled Beyond Apollo: Moon Tech Takes a Giant Leap.

The above facts made me curious so I took a quick look at Wikipedia’s page on Apollo’s Guidance Computer (AGC).

This is a photograph of the AGC user interface:

By today’s standards that computer was tiny.

The AGC was used in the Lunar Excursion Module (LEM) – later called the Lunar Module (LM). The LM was the bit that landed on the Moon. Here is a photograph of the LM:

Apollo 16 Lunar Module

The Apollo program is on my mind because this July it will be 40 years since the Apollo 11 mission. Michael Collins, Buzz Aldrin and Niel Armstrong took that small step – the beginnings of humanity’s journey out of the cradle. You may have guessed that I think this event is significant in the history of humanity. It will still be remembered in thousands of years as one of the major milestones in our development.

Incidentally; the guidance computer was one of the driving forces behind early research into integrated circuits – necessary for development of that computer you are using to read this.

Jrefs Youtube account is back

3 April 2009

It was apparently a copyright issue that has been resolved. Is it really necessary to suspend the whole account instead of temporarily removing the videos the is contention about?

Anyway here is a link to the James Randi Educational Foundation (JREF) YouTube account.

Wikipedia has this to say about James Randi.


JamesRandiFoundation YouTube suspended

30 March 2009

I see that The James Randi Educational Foundation channel at YouTube has been suspended. I suspect YouTube has screwed up again. I am watching the situation with the expectation that YouTube sees the error of their ways and fixes this. The JREF is one of the bastions of clear thinking on the internet.


20th March 2009 11:44 UTC – Vernal Equinox

20 March 2009

Today at 11:44 UTC (roughly the same as GMT).

The center of the Sun crosses the equatorial plane from south to north. On the equator the sun passes directly overhead. At the poles the Sun is on the horizon the whole day. On this day the Sun spends roughly the same length of  time over and under the horizon so day and night are roughly equally long at all places on Earth.

Vernal equinox  comes from the latin ver = spring, aequus = equal and nox = night (day and night of equal length).
