How Do Telescopes Work Telescope Construction At Home

By John B Mayall

There are telescopes of several brands that are freely available in the market. However, even for one who wants to construct his telescope at home, there are several viable options.

One way to go about constructing a telescope is to buy each individual component and then assemble the whole structure. The required elements are mirrors, concave and convex lenses, the housing structure, brackets, and some other components. These can all be bought at local shops or in online stores. A comprehensive list of required elements can be downloaded from websites that serve as guides for amateurs looking to build their own telescopes. Books dedicated to this subject are available.

An enthusiast may also want to construct each element by hand at home, though that is an extremely time-consuming process and not the usual home method. It is a cumbersome process to create the housing compartment and arranging each element inside it. If one wants to follow this method, then one must be prepared to face several hurdles in the construction process.

Another method is to make use of telescope kits, which are available in the markets. These kits contain all the required elements and include instruction manuals to guide amateurs working at home. Using kit elements and assembling the instrument is considered a better method than constructing a telescope from individual elements bought separately. Telescope kits are cheaper and far less time-consuming than other methods of telescope construction. They save time spent on searching for each required component. Step-by-step instructions make it possible to work faster, making fewer mistakes along the way. These kits are intended for amateurs, and first-timers not yet experienced in making telescopes. A professional astronomer or one who aims to become a professional may however choose to work from scratch.

The point of consideration now is whether homemade telescopes are better than readymade instruments available otherwise. The simple answer to such a question is that both are almost the same with respect to quality. A homemade instrument displays the same characteristics as a readymade one of the same specification. A telescope made at home will have the same magnification factor, and is simpler to use in comparison to one bought in a shop. In fact, it is not complex at all and is similar to the ones built by early astronomers like Galileo.

The construction of telescopes at home, in truth, is often a joy, and a hobby that many enjoy. Several people consider it akin to an art, and have dedicated themselves to creating perfect instruments at home. Several sites online are a medium for proud astronomers to display their homemade telescopes. There are also web pages in existence that are dedicated guides for amateurs who want to create their own telescopes. Such pages give comprehensive lists of the elements required for its construction as well.

As with any other task, exhaustive research is required before setting out to make a telescope. It is imperative that the builder understands how each element performs individually and how it affects the whole. It also advisable to have storage space for the material required in construction of a telescope. However, despite all the effort that goes into construction of a homemade instrument, the results are reward enough.

WHO’s reaction to H1N1 influenced by drug companies, reports claim

Sunday, June 6, 2010

Reports suggest the World Health Organisation’s declaring a swine flu pandemic was an error driven by drug companies, and lead to unjustified fear. A year after the swine flu pandemic was declared, stocks are left unused and governments try to abandon contracts, pharmaceutical companies have profited at least £4.6billion from the sale of vaccines alone.

Reports by the British Medical Journal (BMJ), the Bureau of Investigative Journalism (BIJ) and the Council of Europe claim that The World Health Organisation reaction to H1N1 was influenced by pharmaceutical companies and that key scientists behind advice had financial ties with firms Roche and GlaxoSmithKline (GSK). These conflicts of interest have never been publicly disclosed by WHO, an apparent violation of its own rules.

The World Health Organisation issued H1N1 guidelines in 2004, recommending countries to stockpile millions of doses of antiviral medication. The advice prompted many countries around the world into buying up large stocks of Tamiflu, made by Roche, and Relenza manufactured by GSK.

A joint investigation with the BMJ and the BIJ, found that scientists involved in developing the WHO 2004 guidance had previously been paid by Roche or GSK for lecturing and consultancy work as well as being involved in research for the companies. “The WHO’s credibility has been badly damaged,” BMJ editor Fiona Godlee said in an editorial.

A report by the health committee of the Parliamentary Assembly of the Council of Europe, a 47-member human rights watchdog, found that the WHO’s reaction was influenced by drug companies that make H1N1 antiviral drugs and vaccines. It criticised WHO lack of transparency around the handling of the swine flu pandemic and says the public health guidelines by WHO, EU agencies and national governments led to a “waste of large sums of public money and unjustified scares and fears about the health risks faced by the European public.”

We’re still in the pandemic

A spokesman for WHO said the drug industry did not influence its decisions on swine flu. Margaret Chan, the organisation’s director, had dismissed inquiries into its handling of the A/H1N1 pandemic as “conspiracy theories” earlier this year, she had said: “WHO anticipated close scrutiny of its decisions, but we did not anticipate that we would be accused, by some European politicians, of having declared a fake pandemic on the advice of experts with ties to the pharmaceutical industry and something personal to gain from increased industry profits.”

Yesterday, a 16-member “emergency committee” consisting of advisors from the World Health Organisation said that the H1N1 pandemic is not yet over. The WHO has refused to identify committee members, arguing that they must be shielded from industry pressure, so possible conflicts of interest with drug companies are unknown. The BMJ report also reveals that at least one expert on the “emergency committee” received payment during 2009 from GSK.

In related news, Reuters reported, Pfizer Inc, the world’s biggest drugmaker, is selling its swine vaccine business to Chinese Harbin Pharmaceutical Group for $50 million.

Gunman kills self and hostage in Texas NASA building

Friday, April 20, 2007

Around 1:40 p.m. CDT, NASA employees reported that two shots were fired in the NASA Building 44 in the Johnson Space Center in Houston, Texas. A SWAT team later reported that Bill Phillips, a contract engineer with Jacobs Engineering, had killed David Beverly as well as himself, leaving a female hostage physically unharmed.

Phillips entered a conference room with gun drawn and ordered all but one person out. Phillips barricaded himself on the second floor of the two-story building, with David Beverly and another female hostage. The building was evacuated and police were summoned. NASA security, Houston police and a SWAT team were on the scene.

Houston news reported at 5:22 p.m. CDT that Bill Phillips, the gunman, and David Beverly, the hostage, were both dead. Police reported that the SWAT team heard one shot and decided to engage, but before they reached the room they heard another shot. When SWAT reached the scene, the male hostage was dead from a bullet to the chest, the gunman was dead from a bullet to the head, and the female hostage, Fran Cranshaw, was gagged and bound to a chair with duct tape, but was otherwise unharmed.

All NASA employees had first been warned to stay in their buildings but were later told by NASA they were free to go home if their working day was over. Mission Control locked its doors during this incident, as this is a standard procedure in such situations. No NASA Mission has been affected by this incident, according to NASA.

In the first press conference, police said that communication to the gunman had not yet been established, but that negotiators had already tried it two times unsuccessfully.

The motive of the hostage-taking, and whether the three people had any connection to each other, is currently under investigation.

The Houston Chronicle reports that last month Phillips had received one e-mail from his employer, Jacob engineering Inc., “describing problems with his work and offering suggestions on improvement.” Jacobs printed that e-mail on March 18, the same day he bought the 38-caliber gun that police suspect was used in the shooting.

Despite reassurances by Cranshaw and Beverly, Phillips would not believe that management was not going to fire him, according to Cranshaw. During the 3-hour standoff, Phillips used a dry-erase board in the room indicating he was tired of being called “stupid,” police said last Saturday.

Michael Sampson, the co-manager of the space agency’s Electronic Parts and Packaging Program, who had known Beverly for ten years, described him as friendly, peaceful person, with a positive attitude to his co-workers.

Relatives describe Phillips as a loner who always kept to himself. He had lost his father in 2003, but had decided not to return to his hometown in Tennessee. Smith, a cousin of Phillips, remarked that in the Christmas card he had received from him last year, Phillips said that he was feeling lonely and without family, but nothing in the card suggested anything so tragic.

ICANN top-level .xxx domain name not dead yet

Sunday, January 7, 2007

The Internet Corporation for Assigned Names and Numbers (ICANN) announced Friday that its vote in May last year was not to reject the creation of ‘Triple X’, a top-level domain (sTLD). Rather, the corporation voted “not to approve the agreement as proposed, but did not reject the application”.

A revised proposal for the .xxx domain is open to public comment until February 5. The revised proposal appears to have hinged on efforts by ICM, proponents of a voluntary adult top-level domain, to promote enforcement in the following areas:

  1. Prohibit child pornography
  2. Require clear labeling
  3. Support development of user empowerment technology
  4. Ensure that the child advocacy and free expression communities are involved in policy development for the sTLD.

Who, or what, ICM is remains unclear. The home page of ICM states that, “The .xxx top-level domain will create a clearly identifiable area of the Internet so that Internet users can be more informed when choosing to select or avoid adult entertainment sites.”

The estimated $12 billion per year in revenues generated by on-line pornography could come under the scrutiny of unknown ICM, to whom ICANN proposes delegating responsibility to an organization, or individual, that has nothing more to say about themselves on their website than the background of their leaders.

Men isolated to mimic Mars flight

Monday, June 7, 2010

Following a similar experiment in 2009, six men entered an enclosed room in Moscow last Thursday to simulate a flight to Mars. The Mars-500 team consist of a Chinese man, a Frenchman, an Italian, and three Russians. Only the Chinese man, Wang Yue, is a trained astronaut. The six waved goodbye, crying “see you in 520 days’ time!”.

According to Wang, not being able to see their families and friends was one of the greatest challenges, although e-mail is allowed during the experiment. Both Wang and the Frenchman, Romain Charles, expressed pride to be part of this experiment. Wang said, “it will be trying for all of us. We cannot see our family, we cannot see our friends, but I think it is all a glorious time in our lives.”

The joint-effort project is being organised by the Russian Institute for Biomedical Problems (IBMP) and the European Space Agency; the goal is to study physical and psychological effects on would-be astronauts. All six men speak reasonable English; however, as Russian is another primary language for the simulated trip, Russian crew member Sukhrob Kamolov said body language will be used should they fail to understand one another.

Food for the volunteers will be rationed as it would in a real Mars mission. All supplies were supplied by China and loaded into the ‘simulated spacecraft’ prior to the beginning of the experiment. For backup, China is sending three mission support staff to Russia.

No women are included in the crew, excluding issues relating to a mixed-sex crew from the study. During a similar experiment in 1999, a woman complained that the captain attempted to kiss her.

Following 250 days of “travelling” to Mars, the group will split. Three will stay in the “spacecraft”, the other three going to the surface of “Mars”. Only two will actually leave the “spacecraft” to study the surface of “Mars”. After a month, the group will go through the return journey simulation, a 240 day trip. The men will follow a strict timetable, with 8 hours each of sleep, work, and leisure each day.

A Murder Mystery Puzzle For You To Solve

By Gary Simpson

Anybody who has visited my website at Motivation & Self Esteem for Success or has read any of the many articles I have written will realise what a proponent I am of reading books and educating yourself. If you want to become successful at anything you simply must do this, in my opinion.

However, not everything you learn and/or read is of equal value. As the world’s store of information becomes exponentially greater, almost by the minute, you must learn to become more and more discerning about what you read and believe.

With this in mind, I believe you need to understand five basic things:

1 – Find out what you are interested in,

2 – Look for information on subjects of interest,

3 – Search for constants to confirm your understanding,

4 – Filter out needless information and garbage from real knowledge,

5 – Act only on what you believe to be the truth.

[youtube]http://www.youtube.com/watch?v=flgeWsQM0Cg[/youtube]

To demonstrate the above points I have devised a little mystery for you. I hope you will find this not only a stimulating exercise but also a bit of fun.

Listed below is a set of 16 clues to a murder investigation involving the occupants of five consecutive houses. They are all you need to solve the mystery of “Who Killed Who.”

The “Who Killed Who” Murder Mystery Clues:

1- The Motivator plays bowls on Saturday.

2 – When facing the houses, the house with the blue roof is immediately to the right of the house with the grey roof.

3 – The man in the middle house plays golf twice a week.

4 – The woman in the house with the blue roof is a hockey player.

5 – The Scientist lives in the first house, near the cheesecake shop.

6 – The person who drives a Jaguar lives next to the man with the Dalmatian.

7 – The person who lives in the house with the red roof drives a Renault.

8 – The Scientist lives in the house next to the house with the green roof.

9 – The Accountant’s house has a Volkswagen parked in the driveway.

10 – The man who drives the Lexus owns a Shitzhu.

11 – The Doctor lives in the house with the brown roof.

12 – The house with the Renault in the driveway is next to the house next door to where the Doberman lives.

13 – The murderer’s Poodle went missing on Sunday.

14 – The Lawyer hates dogs but loves cheesecake.

15 – The man who drives the Porsche is a keen jogger and was seen running past the victim’s house just after midnight on Wednesday.

16 – The victim used to enjoy playing lacrosse on Tuesday evenings.

If you solve the mystery all the clues will fit together like a successful crossword puzzle. If you are having difficulty you can email me for some clues.

If you would like to drive all your friends crazy with this you may copy it and send it to them providing nothing is changed and the full contents, including the resource box below remains intact.

Happy problem solving and remember – books are a wonderful source of education.

Hint: Make a drawing of the five houses.

Manitoba’s flood creating hazardous conditions

Tuesday, April 14, 2009

The Red River at Winnipeg is almost clear of ice blocks and ice jamming, however there are still dangers from the Red River flood.

Ice blocks which were as high as two storey buildings were ripping out trees, fences and railway ties. “You’ll see huge pans of ice standing vertical, up to 20 feet (6.1 m) high,” said Steve Topping, an official with the provincial Water Stewardship Department. “Ice was shoved up on the shore and took out trees with a very devastating effect. It has changed people’s view of the river.”

“It is incredible, the force. One piece of ice pushed out of the river about 20 feet. You watch the force push this up right in front of your eyes,” said Dean North, of the Selkirk Golf and Country Club.

Royal Canadian Mounted Police are ticketing sight seers who are driving through road closure signs and approaching excavators, cranes and crews breaking up the ice. Vehicles, people, boats, and kayaks are getting in the way.

An eight year old boy is in critical condition after slipping on a culvert Thursday. He was pulled underwater by the speed of the flowing water and remained under for about five to ten minutes until adults could rescue him. The air ambulance supplied by Alberta’s STARS (Shock Trauma Air Rescue Society) remains in the city of Winnipeg, Manitoba.

“This is not a spectator sport. It’s not about getting the best pictures for the family albums. I know floods are seen as a bit of an event, but some of the instances I’m hearing about, people should give their head a shake, they really should,” said Steve Ashton Manitoba Emergency Measures Minister, “Those who fall into the river or get into trouble in another way would be not only endangering themselves but the emergency response crews trying to rescue them. I don’t want to see a situation … where we’re trying our darndest to prevent flooding and save lives and somebody [who] decides to go have a white-water experience ends up killing themselves.”

Early Easter Sunday morning floodwater reached the rural municipalities of St. Andrews and St. Clements north of Winnipeg. Residents were sent an evacuation advisory Good Friday, however some residents remained. Rescue efforts commenced Saturday night to find those stranded and unable to leave as their vehicles cannot travel in the swollen overland floodwaters. Some people were rescued from roof tops as entire houses were swept off of their foundations by the large ice blocks hurtling down the river.

Highways in the area remain closed. Neil Gobelle, of Manitoba Infrastructure and Transportation said to “definitely continue to watch the Red River Valley and north of the city up in the Selkirk area. Things are changing quite a bit, quite quickly, so we’ll keep an eye on those areas.”

As of Easter Sunday, Winnipeg is expected to be ice free on the Red River. The River rose 4 feet (1.2 m) in the course of 24 hours. Rain is in the forecast and the higher temperatures of 17 °C (62.6 °F) will cause melting of snow and ice.

A weather system caused by La Niña is being watched by the United States National Weather Service and its potential effects between April 16-18 for residents along the Red River Valley. “We want people to be aware there is a very real possibility of the river going higher than what is out there,” said Mark Ewens, data manager at the NWS, “To have spring floods like this back-to-back is just an unfortunate series of events that have come along to plague us this spring. We’re wanting people to understand that this is a potentially serious problem.”

Peace tax campaigners turned down by UK judge

Friday, July 22, 2005

The Peace Tax Seven, who are campaigning to have the 10 per cent of their taxes which go to Britain’s defence budget diverted to non-military uses, have had their case rejected by a High Court judge.

The judicial review was called for under article 9 of the European Convention on Human Rights which guarantees freedom ‘to manifest one’s religion or beliefs’ and which was made a part of British law in 1998. The Convention includes the right to conscientious objection and the campaigners claim that this gives them the right not to pay other people to go to war on their behalf.

Their statement to the court said: “We want to make a positive contribution to society by paying our tax in full. We object in conscience to paying others to kill on our behalf, but current tax policy forces us to do just that.”

The courtroom had to be enlarged to make room for supporters and the judge listened to the case for three hours.

Roy Prockter, an accountant and campaign member as well as a Quaker, said that the judge told them that “our case has no possibility of being resolved in the British courts”. According to the Guardian, the judge suggested they take the case to Strasbourg. Roy said that the members were going to take time for reflection as they awaited the written judgment from the judge.
