The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.
What instrument measures time?
Clocks and chronometers? watch, water watch and if non techincal then sun and shadow The instrument used to measure time is called a clock. Time is measured by clocks. watch, water watch and if non techincal then sun and shadow a clock? clock or watch A clock. PW Einstein recommended a clock. An atomic clock. See the related link for more information. As a class, all such instruments are collectively referred to as "clocks". A chronometer. A clock or a watch. A sundial. An hourglass. STOP-WATCH we cannot measure time as it is not a physical quantity... it neither has magnitude nor direction... so it cannot be measured... it can only be seen... hmmm............ a watch is the device used to see time :-) My eyelids. The length of my droopy eyelids tell me it is bedtime Clocks. I use a watch. Clock, stopwatch, pendulum... the list goes on. Hm... I don't know, very hard question. I *think* you use something called....Nah it's too crazy of an idea... Alright fine, I'll say it anyway, I think you use some weird alien device called a timer, or stopwatch? You could either use a watch, a stopwatch, or a clock. Xx livvy xX

What are the names of the planets in our solar system?
Names of the Planets Mercury - named after the Roman mythological counterpart of Hermes, the Greek god of messengers, commerce, thieves, and sports. Named as such because of the speed at which it revolves around the Sun. Venus - named after the Roman mythological counterpart of Aphrodite, the Greek goddess of love and beauty. Earth (also known by its Latin name, "Terra") - named after the titan of the Earth from Greek mythology. Mars - named after the Roman mythological counterpart of Ares, the Greek god of war. Jupiter - named after the Roman mythological counterpart of Zeus, the Greek king of the gods. Saturn - named after the Roman god of agriculture and harvest, Saturn. He is the Roman mythological counterpart of Cronus (Kronos), the Greek titan who fathered Zeus. Uranus - named after the Greek mythological Father of the Sky, Ouranos. "Uranus" is the Latin translation of "Ouranos". Neptune - named after the Roman mythological counterpart of Poseidon, the Greek god of the seas. Jupiter, Saturn, Uranus, and Neptune are all made primarily of gas and are very large. Mercury, Venus, Earth and Mars are small and made of rock. My Very eager Mother Just Served Us Noodles Pluto was considered a planet from 1930 to 2006, but was reclassified as a "dwarf planet", because many Pluto-like bodies were discovered in orbits past Neptune. The dwarf planets are Ceres, Pluto, Haumea, Eris, and Makemake. The names of our planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Pluto isn't really classified as a planet anymore, (which I hate) but it is now a Dwarf Planet. Another way to remember the planets names is to make a cool rhyme or little poem. Like this one: My Very Eager Mother Just Sold Us Notebooks According to the 2006 definition by the IAU, there are 8 "planets" in our solar system: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Furthermore, there are a number of large moons orbiting the gas giant planets, and there are several dwarf planets including the former "planet" Pluto (reclassified in 2006). Many new candidates for the dwarf category have been found past the orbit of Neptune. venus, mercury, saturn, earth, mars,jupiter,uranus,neptune and the sun The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. In 2006 the IAU redefined planets and reclassified Pluto, demoting it from planet to minor or dwarf planet - so now we are considered to have only eight. If there is a ninth, it would have to 1) be in hydrostatic equilibrium, 2) be in orbit around the sun, and 3) to have cleared its orbit. With the reclassification of the term "planet" in 2006, there are only eight planets in the solar system, and Pluto is considered a "dwarf planet". The remaining 8 planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. (see the related question) SUN 1. Mercury 2. Venus 3. Earth 4. Mars ASTEROID BELT 5. Jupiter 6.

Asked in Science, Philosophy and Philosophers
Can you explain Science without philosophy is blind and philosophy without science is empty?
Science without philosophy has no guide (is blind). It researches pointless things rather than what we want to know, like the origin of the universe and how to stop global warming. Philosophy without science has no substance (is empty): As an example, more than 2000 years ago, the Grecian philosopher Democritus came up with the idea of atoms, but it was just an idea without meaning until science developed to support his theory. We are just in a position to understand what is philosophy and science.Just may be a drop in the ocean. So let us allow the younger with their beliefs.Tomorrow these beliefs may correct.

What instrument measures temperature?
Most commonly, a thermometer. Related Information: Thermometers are used to measure the increase or decrease in the temperature of a system as it gains or loses internal energy. An alcohol-in-glass thermometer has been the most common personal instrument used to measure temperature. Mercury thermometers are still around but are no longer offered for sale. Today, digital devices are available that scan the forehead or ear. Some other devices used to measure temperature are: Radiation pyrometer, for extremely high temperatures; Glass thermometer: mercury or alcohol; Thermocouple; Thermistor (thermal resistor) Bimetallic strip; Bimetallic spiral; Platinum resistance thermometer (a resistance detector); Examples: A mercury in glass thermometer uses mercury liquid contained within its glass structure to be subjected to heat. the heat causes the mercury fluid to expand along the glass tube and the total amount of expansion can be seen as a measure along the accurate scale of indication. This is a direct indication of the effects of temperature. A more complex method of measuring temperature could be a thermocouple measuring device. A thermocouple consists of 2 dissimilar types of metal materials in the form of wires , which are joined at 1 end by weld/ fusion. this single joined end is called the hot junction. The other end of the 2 wires are then terminated at separate junctions; as in a electronic terminal block. This end of the 2 wires can be called the cold junction. For most accurate temperature measure, I think temperature sensor is the first choice.
How does cloudy weather affect photosynthesis?
Photosynthesis is the process of taking water and light and turning it into energy in the form of sugar. So, if plants don't have enough light, they wont be able to prodce sugar. They still get some light when clouds are around, but not enough for them to be able to create a lot of the product. ********* Light is a limiting factor in photosynthesis during cloudy weather.
Why are light and heat not considered matter?
What i understand is that there is noting call "Light" or "Heat" its just the "Space",. "Space" created between sub atomic particles and atom we understand and call it "Light" and our eye recognizes it - and "Space" created between atom, molecules and cells we feel it and call it "Heat" - our cells / skin feels it IF "Light" is a "particle" or "wave" then you should not see the same star from just one feet away - your eye should loose the particle as it should have gained a little space during its million kilometer journey. Rajeev. Colombo. OLD reply >> Light (including all forms of electromagnetic radiation) is not considered matter because it has no rest mass. Heat doesn't have rest mass either, in fact it is nothing other than the random motion of atoms. These things have energy. They interact with other stuff. But they aren't matter because they aren't what material objects are made up of. Alternatively: Light and heat are not tangible things that you can see, touch or weight. One can not chemically isolate atoms of heat or light. There is no official answer to this question because everyone just takes is as a given fact.
Asked in Science, Biochemistry
Which process converts oxygen and food into cellular energy?
That process is called as biological oxidation. Glucose is the best example of biological oxidation. Here the end products are same. They are water and carbon bi oxide. In the biological oxidation the energy is released in step wise fashion in multiple steps. In the chemical oxidation the energy is released in single step. The amount of energy is exactly same in both the processes. Chemical oxidation is like jumping from the top of the building. Biological oxidation is like coming down via steps. You come down at the same place. But you may end up in braking your legs in the process of jumping down. In biological oxidation, you do not end up in braking your legs.
Asked in Science, Solid State Physics
What affects electrical resistance?
Primary Factors: For a simple system like an electrical wire, there are three major things which will affect the electric resistance. 1. Resistance of wire conductor depends upon the material of which it is made. 2. Resistance of wire conductor is directly proportional to its length. 3. Resistance of a wire conductor is inversely proportional to its area of cross-section. (At least for low frequency voltage.) Additional: In general every material has a characteristic electrical conductivity (and resistivity) which determines how well it will conduct electricity. Metals have very high conductivities and insulators very low. The geometry of an object affects the resistance with the above-mentioned wire geometry being the most important example. In general the type of material and the geometry are the primary factors in determining the resistance of an object, but there are other effects worth mentioning. Temperature can change electrical properties of a material and there are some dramatic examples such as superconductors. Semiconductors can also have important temperature dependent properties. For most generic materials there is a rise in resistance with an increase in temperature but the effect is not usually large. More exotic phenomena also exist, such as the change in resistance due to a magnetic field or nonlinear conductors which do not have a fixed resistance but rather have a resistance that depends on voltage. Conductivity through a gas is a dramatic example of the latter.
What is auto-traffic?
Traffic exchanges are an easy and affordable way to put eyeballs on your websites. You already know you can get great results from manual traffic exchanges like Soaring4Traffic and ProClickExchange. People sometimes ask me about "autosurfs" or auto traffic exchanges. I own manual exchanges, so I'm biased, I'll say that straight out, but here is my take on auto traffic exchanges. Most people want to use autosurfs because less work is required to use them. Sites are rotated automatically on a fixed timer for your viewing pleasure. You don't have to click surf icons to view the next site and earn credit; your account is credited automatically with each new site. In fact, you don't even have to sit and watch the sites go by either. That's the big draw of autosurfs. You turn them on and forget them. Now, that can save the traffic exchange user some serious time. Turn on a few autosurfs, then concentrate on writing email copy, working on a new splash page or making a few phone calls. Advertise, earn advertising credits, and work all at the same time! Autosurfs are fantastic for multitasking. Or are they? The main draw of using an autosurf is the automation of the site rotation. Why is automation attractive? It frees you up to do other things. If you are doing other things, you aren't viewing the sites. So you don't see the sites, big deal. You still earn credits, and that's what you need, so you can keep your site in rotation, right? What is the main goal of using a traffic exchange? Earning credits is important, but credits are useless if your sites rotate on computer screens that nobody is watching. You want to show your site to people who need your products and services, to people who will opt-in to your email list. If you aren't watching the sites rotate, who do you think would? But hey, like I said, I'm biased, so put it to the test yourself. Track your results in the autosurfs. Compare the results to what you get in manual traffic exchanges. Heck, compare them to your results everywhere else you advertise. You should know what kind of return you get from your various promotional efforts. Another great way for natural traffic is backlinking. Getting higher ranked in the search engines is great for increasing traffic. This is basically having your site added to other high pagerank websites to be crawled by search engines. The object is building links month to month, creating a higher chance you be found all over the web. Autosurfing is time consuming and your site is only seen by other people wanting you to see their website. Most with no interest in anyone elses promotions. HigherMyPageRank.som is my favorite backlink spot around. I highly suggest it! Internal Linking is also one option to that. Reciprocal linking is now penalized by Google Penguin update. Getting links from pages High on there domain authority and also from the businesses in the same verticals as they are the preferred ones in terms of PR of ones home page.

How does a newborn calf knows from where it has to take milk?
Satisfying the need to get sustenance would be considered a basic need for species survival, and thus to some extent it is innate. In the wild, an animal that didn't satisfy the need would perish. Within a half hour or so from birth, the newborn calf will stand up, and start butting its head, and sucking on anything that is nipple shaped (the head butt may help with milk flow). The calf initially won't know to go directly to the utter, but will have some idea of what to look for. The cow may also gently push the calf to the right position, and present her utter to the calf. During this time, cooperation of the cow is essentially necessary. After the first taste of milk, the calf rapidly becomes more coordinated, and learns exactly where to get it. While some cooperation of the cow is still helpful, some calves can learn to snitch a few bites from uncooperative mothers.

Where can you take the WAIS IV IQ test for free?
WAIS-IV stands for Wechsler Adult Intelligence Scale-4th Edition. It a clinician administered test--i.e. it cannot be taken online. The test is only sold to clinicians--licensed psychologists--who are trained to use it. You need to see a psychologist to get it done. Sometimes you can get a free assessment at a university clinic with a Ph.D. program in clinical psychology. However, if you walk in and simply request an IQ test, your request might be declined, just like you might be refused and MRI if you walked into a neurologist's office and asked for one. More often than not, the psychologist will inquire as to why you want the test. In fact, it would probably be a violation of professional ethics to not discuss your history and presenting problems before tests are given.
