Did you know that Americans colloquially refer to the season between summer and winter as “Fall”? |
While Brits prefer the more scientific terms “Autumn”! |
Do you feel that? The crisp morning air is a sure sign that the Fall season is right around the corner. As the days get shorter and the temperatures fall, Autumn heralds its coming with fiery red leaves and bright orange pumpkins. Get yourself ready to fall back into Fall with Holidays on the Net’s fun-filled Autumn tr... |
In 2006, two scientists announced that they had cooked an egg by placing it in between two cell phones. It has been thrououghly disproven and analyzed since the surface of the claim, but it is still an excellent opportunity to use the Scientific Thinking Principles on! |
#1: Ruling Out Rival Hypotheses |
This principle isn't the most relevant because the experiment doesn't exactly prove any hypotheses. But it can still apply to the attempt to cook an egg between two cell phones because there could be other effects causing that outcome. |
#2: Correlation vs. Causation |
There are so many other reasons that the egg could've cooked! Maybe it was really hot out? Or the cell phone egg set up was within a microwave? Not the most probable of all possible causations, but it proves the point. There could be many other ways this egg could've cooked (or in actuality, the fact that it didn't coo... |
This claim is very out there so it has a really good chance of being able to be falsified. As we will see in #4, after replicating the incident one can find almost instantly that it is in fact a hoax. |
As many people did, reproducing the egg cooking experiement will prove that it is in fact a hoax. Every reproduction that was prodcued failed to yield the same results as the first, which made everything make sense when the site's webmaster that published the article stepped forward to say it was in fact completely fak... |
#5: Extraordinary Claims |
The claim that you can cook an egg with two cell phones is pretty extraordinary yet there is no extraordinary evidence to back it up! In fact, it is just too extraordinary to be real. |
#6: Occam's Razor |
In my mind, the simpliest explaination would be that it simply is not true. The end. |
I'm not going to lie, if this claim was true I would be thrilled. In addition to being in awe of the power of technology, it would make cooking meals for myself in my dorm room a whole lot easier! Unfortunately though, this is a hoax. With the help of the Six Principles of Scientific Thinking, I will never fall for thi... |
How To Win At Science Fairs (Dec, 1960) |
How To Win At Science Fairs |
by Ronald Benrey |
YOU CAN WIN at a Science Fair as long as one thing interests you more than winning does. This is your project itself. It is going to be judged on scientific thought, creative ability, and presentation. You will really have to know the field your project is concerned with. This takes effort. Since you lack the means of ... |
As a reader of Electronics Illustrated your project will probably deal with electronics or applied physics rather than with biological or earth sciences. Select your topic carefully from a broad subject that really interests you. A massive effort in the direction of a passing fancy will result in a mediocre project at ... |
To ease financial strain, plan now to build your project over a long period of time, say six months, on a pay-as-you-build basis. |
Once you have a rough idea of your project’s general form, don’t dash into construction. |
Visit technical libraries and learn all you can about current professional work in the field, and its technical jargon. This will give you much important information and helpful hints, and when you finally face the judges, you will know your subject. |
Here is a prickly question. It is up to you to be realistic and honest with yourself when you choose a topic. Your science teachers and advisers will certainly be helpful, but the final decision must be yours. In other words, if you have never handled a soldering iron before, don’t take on a project requiring elaborate... |
Another touchy subject: discussion of this often scares off good potential science fairers. Nobody requires or expects a science fair project to produce a radical new scientific discovery. However, this does not imply that an entrant can’t find a new angle on an old problem. Merely duplicating a project described in a ... |
Your project should be well presented and look impressive, but impressive need not mean expensive. Judges seldom look twice at an exhibit loaded down with excess and borrowed equipment when the same results could have been obtained more economically and without false show. Novel use of common materials shows creative a... |
IS YOUR WINNING PROJECT HERE? |
RADIO TELESCOPE: Home-built sensitive low-noise receiver, simple antenna system. Try to make simple “radio map.” |
GUIDANCE SYSTEM: For model ear. Can be programmed to run around science fair grounds without hitting anything, or to reach pre-chosen destination. |
SOLAR CELLS: Home-built unit as part of demonstration of basic physics of solar cells: display on recent professional research results: off-beat practical applications (eyeglass type hearing aid?). |
MOON MOUSE: “To be landed on the Moon. ” Self-propelled, radio controlled from Earth, instrumented and transmitter equipped. Some functions solar powered ? |
These are only suggestions. You may come up with ideas regarding fuel cells, space communications, navigation, etc. |
With the development of science and technology, computer has become more and more popular in our daily life, which is intended to be a part of our life. But at the same time it also brings the safety problem, because increasing number of bad people would like to break into computer systems to steal the secret informati... |
What is malware? In fact malware, short for “malicious software”, is any kind of software which is installed without your complete permission and is not in need at all.The famous malware areviruses, worms, and Trojan horses, which are almost known to us all. Even though you are not familiar with them, you must have hea... |
2 antispyware software |
Antispyware software helps protect your computer, and prevent the pop-ups, slow performance, and security threats caused by spyware and other adverse software. Every computer user must keep antispyware software up to date in order to keep in touch with the latest spyware. Aimed at protecting our computer, we could use ... |
A firewall is used to help screen out hackers, viruses, and worms that try to attack your computer through the Internet.In fact, if you are the one who use the computer at home, the most efficient and important step is to enable firewall when you start your computer. A virus will slip through and infect you; the only e... |
4 antivirus software |
Antivirus software is a kind of computer program which can be used to test, defend, and take actions to remove or delete malicious software program. As we all know, computer virus is some programs, which can specially disturb computer operation. So we should update antivirus software in regular time to prevent against ... |
5 Windows password |
Besides the above mentioned software, you could have an alternative at the same time, namely Windows password. With a password like this, you can prevent your privacy from being let out or being viewed. Of course you should set up a Windows password reset disk to set the password reset in case that you forget it. |
As a computer user, you should have a general knowledge of these safety terms so that you can protect your computer better. And with these terms, your computer can be protected better than that without them. In a word, please have a brief understanding of them in the first place, and then you could know how important t... |
Ever wondered what white tea is? Why we call it white anyway? Here are a few interesting facts about white tea, made from the plant Camellia sinensis: |
- White tea is similar to green tea in that it has undergone little processing and no fermentation whatsoever. |
- The leaves are harvested before they open fully, when the unopened buds are still covered by thin silvery white hair. Hence the white tea name. |
- White tea has a subtle and slightly sweet flavor that sharpens the senses without overwhelming the tongue, whereas green tea has a “grassy” taste. |
- There is 25% to 30% less caffeine in white tea than in green tea, though it depends on the variety. |
- White tea health benefits are the highest among the tea family¹. |
- It is more expensive than green or black tea because white tea is scarcer. Yet, at Savorique, white tea is as cheap as black or green tea. |

.8grams X kilogram of body weight/day |
How to convert pounds into kilograms: #pounds/2.2 = kg |
For example someone who weighs say 110 would be 50kg. So we take 50kg and multilpy that by .8gm and they should be getting about 40 grams of protein a day. Low protein diets can result in weak bones, muscle wasting, and decrease in time for wounds to heal. Protein is essential in the diet and having enough is very impo... |
If you are taking a protein supplement in powder try to find one that does not have any added saturated or transaturated fats. There are some protein supplements out there that are made for gaining weight so they will have additional calories and fats in them. So make sure you read the label and everything says 0 excep... |
This brand is an excellent choice and very safe : |
Just remember to read label and consult with your doctor if it is safe for you to take a protein supplement. |
The following foods are excellent sources of protein: |
- cottage cheese |
- nuts and seeds |
- soy beans |
- Greek yogurt |
Make sure at every meal you have a protein, a healthy carbohydrate(whole wheat or whole grain), and good fat. (monounsaturated fats) Keep your meals and snacks balanced so you can stay full and not feel hungry throughout the day. |
Our opinion: Fostering better nutrition is a key to reducing public health costs. That makes the scarcity of large grocery stores in some urban neighborhoods, especially poor ones, a matter of public policy. |
It’s easy, and comforting, to assume that in an modern, industrialized nation, everyone eats well. Surely with programs like food stamps, even needy people are doing OK, right? |
More than 40,000 people in Albany and Schenectady live in what are known as food deserts — places where a grocery store is at least a mile away. Many are poor. The U.S. Department of Agriculture estimates that about 3,700 of the more than 23,000 people in Albany who don’t live near a large grocer are poor. In Schenecta... |
That’s not just an inconvenience. It’s a public health issue in a society where the problems associated with poor nutrition and obesity are linked to the growing cost of public health care. |
One suggestion for alleviating the problem comes from the American Cancer Society, which is reviving the controversial idea of a tax on soda and other sugar-sweetened drinks. The group suggests using the tax to help fund and evaluate child obesity programs. An even more productive use might be to devote a portion of su... |
It would seem doubtful, though, that the state Legislature will be any more inclined to implement a soda tax than it was last year, when it refused to do so even with the prospect of raising $400 million in new revenue and even with the urging of the state health commissioner and then-Gov. David Paterson. |
That doesn’t mean it’s not worth trying for a soda tax — encouraging kids in particular to cut back on sugary beverages is not a bad goal at all, nor is raising funds that could be used to promote a healthier citizenry. But the more likely reality is that New York and communities will have to find ways to do something ... |
Here’s one direction: Since last March, Capital District Community Gardens has been supplying nine convenience stores and markets with fresh produce under a five-year, $175,000-a-year grant from the state Health Department that also helps underwrite fitness programs. Veggie Mobile Sprout, as this program is called, del... |
How many more ideas to promote healthy and affordable food choices are there that might perhaps benefit from some initial public investment or other support? Why not make identifying and nurturing those ideas part of the mission of local community development or economic development entities? |
Funding for such programs would not be handouts; beyond improving nutrition and reducing obesity with a long-term eye toward reducing public health costs, they would help get greater value out of the public assistance that goes to people in low-income neighborhoods. |
Sounds like a shopping cart full of public interest to us. |
Yesterday’s House passage of cap-and-trade legislation designed to confront climate change is a landmark achievement, the first tangible step taken by the country that emits more greenhouse gas per capita than anyone in the world. |
The bill itself still faces a tough test in the Senate. Passage is far from assured, and without similar actions by other major emitting countries, it won’t mean much. But it does finally demonstrate to the rest of the world that the United States is prepared to do its part, which puts the pressure on them to follow su... |
The bill itself, the product of a thousand political compromises, also isn’t perfect. But it also isn’t what its hysterical opponents claim it is. As Bryan Walsh acknowledges in Time: |
… critics have vastly overstated the likely cost. In fact, they’re all but lying. During the House debate, Republican whip Eric Cantor, using numbers from an American Petroleum Institute study, said that the bill would eventually cost more than $3,000 per family per year — but those numbers assume that billions of tons... |
When opponents are forced to lie so blatantly — in this case exaggerating the likely cost 17 times over — they don’t have much of an honest argument. |
Just as there are many variants and forms of electronic malware and Internet-based threats around the globe, so there are many forms of protection against these threats. Signature-based detection is one of the multifarious forms of defense that have been developed in order to keep us safe from malicious content. |
Although signature-based detection can be argued to have been overshadowed by more sophisticated methods of protection in some environments, it remains as a core ‘technique’ featuring in the anti-virus controls of packages and suites that work to protect a user’s system today. |
How does signature-based detection work? |
Signature-based detection works by scanning the contents of computer files and cross-referencing their contents with the “code signatures” belonging to known viruses. A library of known code signatures is updated and refreshed constantly by the anti-virus software vendor. |
If a viral signature is detected, the software acts to protect the user’s system from damage. Suspected files are typically quarantined and/or encrypted in order to render them inoperable and useless. |
Clearly there will always be new and emerging viruses with their own unique code signatures. So once again, the anti-virus software vendor works constantly to assess and assimilate new signature-based detection data as it becomes available, often in real time so that updates can be pushed out to users immediately and z... |
Next-generation signature-based detection |
New variants of computer virus are of course developed every day and security companies now work to also protect users from malware that attempts to disguise itself from traditional signature-based detection. Virus authors have tried to avoid their malicious code being detected by writing “oligomorphic“, “polymorphic” ... |
Despite these developments, the Internet at large does of course still function on a daily basis. Populated as it is by users who not only have up to date security software installed, but also by those who have educated themselves as to the type of risks discussed here. |

Like many of us, scientific researchers tend to be creatures of habit. This includes research teams working for the National Oceanic and Atmospheric Administration (NOAA), the U.S. government agency charged with measuring the behavior of oceans, atmosphere, and weather. |
Many of these climate scientists work with massive amounts of data – for example, the National Weather Service collecting up-to-the-minute temperature, humidity, and barometric readings from thousands of sites across the United States to help forecast weather. Research teams then rely on some the largest, most powerful... |
Given the reliance on HPC resources, NOAA climate researchers have traditionally worked onsite at major supercomputing facilities, such as Oak Ridge National Laboratory in Tennessee, where access to supercomputers are just steps away. As researchers crate ever more sophisticated models of ocean and atmospheric behavior... |
Now, NOAA is using a super-high-speed network called “n-wave” to connect research sites across the United States with the computing resources they need. The network has been operating for several years, and today transports enough data to fill a 10-Gbps network to full capacity, all day, every day. NOAA is now upgradin... |
“Our scientists were really used to having a computer in their basement,” says Jerry Janssen, manager, n-wave Network, NOAA, in a video about the project. “When that computer moved a couple thousand miles away, we had to give them a lot of assurances that, one, the data would actually move at the speed they needed it t... |
The n-wave project means much more than just a massive new data pipe. It represents a fundamental shift in the way that scientists can conduct their research, allowing them to perform hugely demanding supercomputer runs of their data from dozens of remote locations. As a result, it gives NOAA climate scientists much mo... |
“For the first time, NOAA scientists and engineers in completely separate parts of the country, all the way to places like Alaska and Hawaii and Puerto Rico, will have the bandwidth they need, without restriction,” says Janssen. “NOAA will now be able to do things it never thought it could do before.” |
In addition to providing fast, stable access to HPC resources, n-wave is also allowing NOAA climate scientists to share resources much more easily with scientists in the U.S. Department of Energy and other government agencies. Ideally, this level of collaboration and access to supercomputing resources will help climate... |
Powering Vital Climate Research |
The high-speed nationwide HPC connectivity capability provided by n-wave is now enabling a broad range of NOAA basic science and research activities. Examples include: |
- Basic data dissemination, allowing research teams to collect up-to-the-minute data on ocean, atmosphere, and weather from across the country, and make that data available to other research teams and agencies nationwide. |
- Ensemble forecasting, where researchers run multiple HPC simulations using different initial conditions and modeling techniques, in order to refine their atmospheric forecasts and minimize errors. |
