Why we learn Science.

Science is the furthering of human understanding. So we learn science to further our understanding of our world and beyond. Humans are naturally curious creatures so its something that the basis for science is curiosity. You're curious about how the amount of sunlight affects a plant, so you research your interest, form a hypothesis, execute a series of experiments to gather data, analyze that data, and form a conclusion based on your experiences and what the data has to say. But science is not just a process used to figure things out, it's much more. It's a way to learn, to grow as a civilization, to celebrate new discoveries. Science is not just facts and numbers, but an advancement of human kind. Science has evolved alongside us from when we as humans were young (ancient times) and still figuring out what makes it rain, or the simple things about the earth that we've known since we were little. It has grown with us throughout the years and now we use it to discover life on mars, to create a cellphone or computer, or desining the worlds tallest building to withstand the elements and gravity for decades. Some could care less about science, thinking it doesn't apply to them and wondering as we all have at one time or another,"why should I care? It's not like I'm going to use THIS in the job I want." But to compete in a world like ours, needing to have a firm grasp of science is crucial for success in anything. That is why we need to learn science.

Electromagnetic Force

Electromagnetic force is simply the attraction that occurs between two oppositely charged particles. You have a positively charged particle and negatively charged particle, electromagnetic force causes the two to be attracted to each other.

Some examples are, as many of you said, magnets. You have positive and a negatively charged sides, and that when two oppositely charged sides come near each other they are attracted to one another and thus want to come in contact. Another example is the attraction between the electrons and the protons in an atom. We all know the charges of the two particles and that they are attracted to each other, but if there wasnt a thing such as the electromagnetic force, our universe would just be a bunch of protons and neutrons and electrons floating around in space (if there would be any).

The force has changed our world in many ways. For one thing it allows atoms to form and combine with other atoms and make up everything in our world and beyond. It also works with electricity with the posative and negative wires and batteries and how you connect the + with the - and the - with the +. Without that, all electronics wouldnt work at all.

Global Warming. Devastating Reality or Over-hyped Natural Cycle

Okay so after reading the links and other peoples blogs i just get confused, but im more leaning to the idea that global warming is happening. I say that im confused because most of the scientific findings contradict each other and so in my mind, cancels each other out. People say global warming is happening and we're to blame and if we dont do anything about it now there will be irreversible changes like the icecaps melting and florida being underwater and the poor polar bears going extinct and the earths surface resembling that of mars! Others say that its just a natural trend that will correct itself eventually and that we have nothing to worry about.

I still sort of wonder if WE ARE the cause of global warming or is global warming, and cooling, a natural cycle thats been going on around us forever, but that with our improved technology, we've just noticed the changes in the last century or so. If it is a naturally occurring cycle, have our recent actions in the last century caused the changes to be more emphasized. Like the emission of CO2 in the air since the industrial revolution, increasing the greenhouse effect every warming cycle, causing the earth to take longer to cool off and so when the warming cycle comes around again the earth is still relatively warm from the last cycle. So its like taking 4 steps forward 2 steps back, and so on over a period of time, if that makes any sense to you.

Secondly i can somewhat see how he government could gain from the whole fear factor thing with the public. You know like winning votes for candidates who are all like "we need to stop this from getting worse or our children will have to live in a dismal future that we caused." And so people will vote for that person because they believe that person will do something to change the future for their kids. Also as i stated above the fact that scientists findings dont really agree with each others even though their data comes from the same planet puzzles me.

My last thought is about whats happening now and what we're trying to do to lessen the effects now and slow it down.....if possible. I think that what we're doing now with our technology is awesome by making things all eco-friendly and energy efficient. Saves a lot of money, but also requires a lot of money to discover. Even if global warming isnt as dire as some predict it to be, it would be good to have better efficient technology for the future. I just feel bad it takes a possible global catastrophe of epic proportions for us to finally get it through our heads that we have an impact on our planet and that we have to change our current habits and ways of doing things if we want to continue living as we are.

What Causes Change cont.

Okay so after reading some other peoples blogs i've decided that my answer could use a tweak. My original answer was "anything can cause change" but apparently that was too general and that we should really try to look for one single answer if possible that could work for almost every situation like mr voight said "We should be able to take this answer and find examples in politics, nature, economics, music, art, daily life, etc..." I could simply say God creates change and that would work for well anything and everything, but i wont because thats religiously based and wont work in the scientific community. I will say i agree wholeheartedly with what tara had to say about time not being the cause of change, but rather the measurement of change taking place. Anyway to save time and keep this short I'll say that my view has changed and that now I think that an action causes change. Without a force that acts upon the whatever it is thats changeing the thing wont change. The action could be from a human, opening a door, turnign up the heat in the house, driving a car that consumes oil which uses up our natural oil supply, ect.... It could also be from nature, like snow piling up on a mountain so much that it causes an avalache, the sun shining and drying up a puddle, the wind blowing and dying the clothes out on the line, a volcano erupting and laying waste to a landscape, also a lightning bold stiking a forrest ravaged by drought and causing a fire. Those are just examples of human and naturual elements, but animals can also change due to actions. For instance a cheetah takes down a young wildabeest, depending on the mood of the heard the others might try to defend that youngling and fight off the cheetah as a group. The change was from a calm peacefull atmosphere to an action packed struggle of life and death. Thats all I can think of for now.

What Causes Change

Well to begin, this is really is a very general question. It could apply to any situation and so any answer can work. That is why my answer to the question "what causes change?" is simply "anything".
Anything can cause some sort of change whether good or bad. Sunlight shining on a plant will cause it to make chloriform which feeds the plant and lets it live. It's raining and the wind blows the clouds away, it stops raining. That is definately a change. In science adding two chemicals together can cause a reaction, a reaction is a change. Adding two or more elements can create an entirely new substance. Ice melting is a change from a solid to a liquid, and water evaporating is a change from a liquid to a gas. Turning the nob on the speaker will change the volume. A ball is standing still and you give it a push. You could get technical and go into all the changes that happen in your body like the brain sending a electric current through the nerves and telling a motionless arm to move an object.
Change is not only just restricted to chemical and physical change but it can also be mental. For a wierd example, right now I'm watching "Wifeswap". You have two "odd" families that are complete opposites, and the wives trade families for one week. For the first few days the new wives must live by the families rules, then they enforce their own rules. Normaly the rules are based on how the wives run their own family. The first few days of the new rules are almost always dramatic, the "wife" gets backlashed mostly from the "husband" and the rules arent really followed. Then as the week goes by there is that one pivitol moment where the family realizes there is another way of doing things and it's like a light went on in their heads. In the end the families dont change entirely but they incorporate the newly learned ways of life and living. That is change. One human influencing anothers mind is probably one of the most important interactions that leads to change in the human race.
Of course there are more examples than the ones I listed. Hopefully you get the idea. Anything can cause change. I believe that "change" cant be started by just one simple thing, if it was it would be mind boggling to trace every action to the begining incident that lead to that dominoe effect of cahnges and effects and the change that was caused by the effect.
