Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

Can you heat water a magnifying glass with an artificial light source instead of the sun?

Sure. But the magnifying glass can't squeeze any more heat out of your light source
than what the source has without the magnifying glass.

The only thing the magnifying glass does is take all of the light ... and maybe heat ? ...
that hits the magnifying glass and focus it down to a very small area. It has no more
heat or light to work with than what enters the glass.

The most efficient way to heat water with a light bulb is to shine the bulb straight up
and hang the pot over it.

How can you use the scientific method outside a class room?

Science is useful everywhere. Having good knowledege is very importanat as it can benefit you when you need it. Like for example, you are lost in the forest and need food, shelter and water. You will know if you learned that if you are lost in the forest at dusk, the sun would be at the west. If your home is east you can go the opposite way. If you are lost at night , you can follow the north star. You might also need knowledge on poisonous fungi and plants and be alert of edible and inedible stuff.

What is the difference between parameter and sample?

A parameter is an attribute that refers to the entire population. (For example, the mean price of all motor vehicles in a city). A sample is collected from this population of all motor vehicles in that city to compute a statistic (here, the statistic is the average price of the vehicles in the sample) which is representative of the true price.

What problem did Einstein solve using the scientific method?

Einsten was a theorist, not an experimentalist. He developed theories to explain other people's data, which doesn't really fit in with the formal scientific method taught in schools.

What is the common salt that is present in permanent hard water?

The common salt present in permanent hard water is calcium sulfate (CaSO4) and magnesium sulfate (MgSO4). These salts contribute to the hardness of water by forming insoluble precipitates with soap, leading to the formation of soap scum.

Can the scientific method be used to test supernatural phenomena?

Yes, the scientific method can be used to test supernatural phenomena. So far studies conducted in a scientific manner suggest that supernatural occurrences do not exist.

Is it true that there are people out there who can look exactly like you but you guys wont like the same things you guys just look alike?

... Sigh. America. How ashamed i am of thee sometimes...

First of all, there are no two people who are exactly alike in looks. Its physically impossible, even for identical twins, to not have an outstanding feature from the other (One Twin may be taller, or more commonly, have freckles or moles in different places than their sibling)

Second of all, If you really think physical appearance determines intrests/activities/taste, then you are shallow. Each human being is unique in that you have a soul, whether you believe in a greater power or not (Personally, i am an athiest) you have a soul, and the decisions, the intrests, the realtionships and connections that you have shape your soul into a unique body. The Idea of Perfectly (Mentally) Identical Twins is... Orwellian. No two people on this earth are the same, whether it be by looks, intrests, taste, or any other human attribute. Its the beauty of life, that each being is in and of itself a beautiful, completly unique person.

Think Snow Flakes.

Now, please Go to your local Library and read a book, preferably not one involving large text and pictures -_-

What are two parts of a scientific name?

The first part of the scientific name is the genus name. The second part is the species name. If there is a third part, it refers to the subspecies name.

Here's an example:

Canis lupus familiaris

"Canis" is the name of the genus that the domestic dog belongs to, along with wolves and coyotes. "lupus" refers to the species within the Canis genus that wolves and domestic dogs belong to. "familiaris" refers to the subspecies that only domestic dogs, and not wolves, belong to. Note that only the genus name in a scientific name starts with a capital letter.

What is the working principle of the kaleidoscope?

A kaleidoscope is a device made of (usually three) mirrors facing each other. In most cases, some small, sparkly matter is put in a slide on the end. Anything on the end is reflected by the mirrors, and the mirrors reflect each other, repeating the image over and over.

Why is the snorg hypothesis not scientific?

There is no experiment or possible evidence that could prove that invisible snorgs do not exist. So the Snorg Hypothesis is not scientific. On the other hand, the "Negative Snorg Hypothesis" (that they do not exist) is scientific. You can disprove it by catching one.

What is the difference between hypothesis and inference?

A hypothesis is a statement of fact or belief upon which further conclusions can be drawn.

An inference is the meaning that I attribute to someone else's statement or action.

How is the scientific method used to study the Bible?

Do you mean you are thinking of forming an hypothesis, gathering quantitative data, and testing it somehow? I have to say that seems like an odd approach to studying the Bible. Or do you simply mean forming questions and then looking for the answers in the Bible? I suppose that would be what the "scientific method" really is about, to state it simply. Well, a scientific approach also should keep personal bias and subjective observations out of the equation, so to speak. That would actually be very beneficial in studying the Bible, I think. You wouldn't go into it with a preconceived intent to discredit it, as it seems some scientifically-inclined individuals have done.

Something I would like to point out about the Bible is that it was obviously not written to be a science textbook. It was written to be understood by people from all levels of learning, from all cultures, all types of people. To me, that is part of its genius.

However, when it does touch on scientific matters it is actually quite factual, matching up with proven science.

Can the scientific method be used to deny or prove the existence of God?

Not conclusively; at least not yet. Otherwise, either atheism or religion would have been universally accepted among people who have learned the relevant topics.

However, if someone claims that the answer is No because no evidence is out there (or has been found), his statement would be misleading. The scientific method is used to seekevidence, not to deny its existence. Such seeking can certainly be attempted.

What steps of the sientific method did Oswald Avery and his associates use in their transformation experiments?

Oswald Avery and his associates followed several key steps of the scientific method in their transformation experiments. They began by making observations about the effects of heat-killed pathogenic bacteria on non-pathogenic strains. They formed a hypothesis that a substance from the heat-killed bacteria was responsible for transforming the non-pathogenic bacteria into pathogenic forms. Through systematic experimentation, they isolated and purified DNA, demonstrating that it was the transforming principle, thus supporting their hypothesis with empirical evidence.
