Do Scientist that do carbon dating take into account possible irregular unrecorder radiation levels that could lead to an innacurate result of the dating test? If they do, how?

I find this statement quite hard to understand. I cant see how he gets from Atmospheric doubling to 50 times the amount of CO2. If the ocean has 50 times the amount of CO2 then surely doubling the atmospheric CO2 would just double the oceanic CO2 not multiply it by 50. Not even that actually as the oceans absorb more the figure would be less. Plus it seems unlikel;y that pumping CO2 into the air very quickly would suddenly, magically, cause the oceans to double their CO2 . Also the ocean can absorb different amounts depending on its temperature - so the more CO2 in the atmosphere or ,even if you do not accept AGW, the warmer it gets - the less the oceans can absorb .Then …

This is a science forum, and as such, in a lot of debates, we ask each other for sources to back up assertions or claims. And the gold standard is, as it rightly should be, papers in peer-reviewed scientific journals. But that shouldn't be where it stops. Just because a source is in a peer-reviewed journal *doesn't* mean it's correct, or even that it's not embarrassingly wrong. Like any website, book, or article, you should read the paper and make sure that it actually says what the person citing it claims, and that it's not complete crap. Consider a recent example: Chatterjee, Templin & Campbell. The aerodynamics of Argentavis, the world's largest flyin…

Simple question really. What is best when giving a scientific talk, such as a group seminar? 1) Blackboard & Chalk, 2) White Board, 3) Computer, Overhead projector & Beamer. 4) Something else(?) I think, based on my own experiences the board & chalk approach is best. It gives one the chance to explore things guided by your audience and the pause due to writing gives them chance to take it in. Downside can be poor writing on the board. What do you think?

The structure of the Earth can be split into various layers as follows, shown at the foot of the page. However, it has been suggested that the temperature of the inner core is made of 'an iron-nickel' alloy with the temperature of the Sun's surface. Two questions arise in my mind: 1. Why is is still solid at temperatures in excess of the melting point of iron and nickel? 2. If it is indeed a solid, what kind of solid can it possibly be? Is it like the solids we experience at the Earth's surface, or does it have unknown and exciting properties? http://en.wikipedia.org/wiki/Inner_core

I don't know if this initial post is clear but I will try to explain what I mean. Newton's Law of Gravity is presumably based on numerous observations and tests which led to the belief of a fundamental Law of Science. What are the steps to make a Law of Science? I am guessing the following: Observation Hypothesis (Tests for Reproducibility) Theory (Tests for Reproducibility, Falsification and Exceptions) Principle (e.g. the Anthropic Principle) Law However, I am a bit confused about the order of events and look for help here.

I am new to this forum, so i want to ask what did you think about difference and similarity between science and history?

I was at the park, when a man from the water company drove in. He began using an orange instrument which looked like those metal detectors I've seen people using. It had a box with a meter on top, only instead of a flat pickup plate at the bottom, it didn't have anything. It just ended with a cap. My friend began talking with him and we found out he was looking for a metal cover that was buried. The instrument was beeping at different rates as he passed this "wand" over the ground but he became frustrated when he couldn't find it. As we watched, he got another instrument that was similar (but yellow) and looked more like a cane without a box on top. It didn't do any…

I read that in the desert, temperature inversion happens mostly on hot days. Why? The desert sand warms quickest, and so has the lowest heat capacity, so should absorb less heat than the air above it does. Why not? Sand normally has a specific heat capacity of 800 joules per kelvin per kilogram. Air normally has a specific heat capacity of 1000 joules per kelvin per kilogram.

A friend I was debating claims that nuclear power is THE answer, and that other countries (not US), use a lot more than us. He then claimed that Canada stores ALL it's nuclear waste in one place the size of a football field. I find this VERY hard to believe. Is he wrong about this? Why are most people opposed to nuclear power (including my science professors), is it the waste or the risk of a meltdown?

Science of Morality, Anyone? Where, in American culture, is the domain of knowledge that we would identify as morality studied and taught? I suspect that if we do not quickly develop a science of morality that will make it possible for us to live together on this planet in a more harmonious manner our technology will help us to destroy the species and perhaps the planet soon. It seems to me that we have given the subject matter of morality primarily over to religion. It also seems to me that if we ask the question ‘why do humans treat one another so terribly?’ we will find the answer in this moral aspect of human culture. The ‘man of maxims’ “is the pop…

Practical tips for skilled skeptics Realize that the need to believe, and serve others, are basic human needs In general our expectations pretty much determine what we see and don’t see (magicians take full advantage of this expectation) Humans lie and they BS (almost always with a vested interest) Under specific conditions hallucinations may occur in healthy people For many people that don’t understand specific phenomena they would rather believe something than say they don’t know Apply skepticism in a very cautious manner to particular subjects e.g. religion, abortion, death penalty etc. Realize you can’t be skeptical 100% of the time as the…

Well....probably. http://www.npr.org/templates/story/story.php?storyId=113159860 "September 24, 2009 Three different space probes have gathered evidence that the top layer of the moon's surface contains hidden stores of water."

1 . is it true that some thing that turns on or off very fast or AC will make radio wave ? 2. modulation is way of putting information on the radio wave? 3. All things have a resonant frequencies ? 4. A resonant is some thing that vibrates when energy of certain frequency is applied to it. 5. A moving or changing magnetic field causes electric current. Note I'm trying find other ways to transfer electricity or cause electric current.I know electric current has magnetic field and magnetic field causes electric current . I also know there is strong relashionship of electricity and magnetism .

Something that might be of interest to those here... a National Geographic special airing on Sunday the 11th October entitled Dinosaurs Decoded. Here is a synapsis of the show: With stunning animation, Dinosaurs Decoded brings to life a vision of dinosaurs unlike any you’ve ever seen before. Groundbreaking work by famed paleontologist Jack Horner, Mark Goodwin, and others reveals dinosaur underwent extreme transformations as they grew. They sprouted and lost horns and bumps on their skulls. And males shed dull colors for startlingly bright ones. A young Triceratops or T.rex may have looked so different from its parents you’d have a hard time recognizing it. …

http://www.scienceforums.net/forum/showthread.php?p=511093#post511093 So what do you think, are economics a scientific field or not? I'm personally going to go with "god no". Economics is not empirical and relies too much on unpredictable human behaviors to ever have testable theories in the way you can in the hard sciences. I think the financial crisis proved very thoroughly that when you try to take scientific modeling and apply it to economics, what you end up with are not reliable predictions about the future.

Tiny houses are nothing new, in Japan they are big (no pun intended) but are often quite unpleasent. Other verstions of the idea such as caravans totally fail. I have what is probbably a new idea. Imagine a single room, the room has waterproof possible pool like walls and floor, nice for an odd shaped swimming pool but no use for a house. Across the bottom of one wall is something that looks like nothing but upon eximation opens into a slot with the edge of a carpet inside, pull at the carpet and it unrolls covering the floor clipping in neer the floor at the other side. You chose the color and style of this carpet on purchising the space and can for a fee have it…

I currently am a fiber installer for one of the largest FTTH deployments in the USA. I would be willing to help anyone understand what goes into deploying this wonderful technology. In return I ask for a challenging and thought provoking environment. Who knows, maybe we can develop new science and technology here on these forums. Every good product started with an idea.
