Using logs I've found that X=(log9/log4)-2 = log9-log4-2. Is this correct?

Homework Statement 4^(x+2)=9 Homework Equations basically all I want to know is what is the best way to go about solving a problem like this. The Attempt at a Solution I know how to convert a problem as such 4^(3x)=10 using. [log(<base>4,10)]/3 = X. however I need some help with...

What the hell?! Thats just sad.

Are they real are what? I've read in various places on the internet that there is a vast amount of energy stored in the vacuum of space that is supposedly extractable and extremely efficient. The top link below contains quite a bit on information about the potential weapons (scalar howitzer...

Oh wow thanks I can't believe the mistake was that simple. If I did multiply 1-(cos^2 (x)) - (cos^2 (x)) + (cos^4 (x)) by cos^3 (x) I would have gotten: 1-(cos^2 (x)) - (cos^2 (x)) + (cos^4 (x)) cos^3 - 2cos^5 + cos^7 which was the correct answer. Thanks.

Homework Statement Express [(Cos^3)x][(Sin^4)x] in terms of cos(x) and its powers:Homework Equations All I used was Sin^2+Cos^2=1 but apparently it didn't work! I probably should have used more identities but I don't know. The Attempt at a Solution I broke the equation into two sections, the...

Well I've read that pole switches are consistent with the alignment of the galactic center which does occur every 25000 years or so.

The core is suspended in liquid like metal so in reality the center of our Earth is just floating around on liquid rock. What happens is that the core will sometimes do a flip and reverse the poles. There is evidence of this in the past and it occurs once every ~25000 years. Whats cool though is...

For Earth's magnetic field I would imagine it more like a sea of liquid metal (iron perhaps?) rather than a synchronized flow influenced by convection currents and such. As far as science knows all magnets must have two poles since a monopole has not been discovered nor created yet.

Well suppose many small black holes are created and collide. Could that pose a problem? Also couldn't it be beneficial if the LHC created microscopic black holes. That way they could be studied with very little risk.

by P=mv i was thinking about the concept that if they are particles and they hit each other with equal momentum then they should 'cancel' each others energies out.

Yesterday I was thinking about electric fields and how similar fields, when intersecting, push away and 'deflect' each other. If we were to take two fields of equal magnitude (and charge since I am using an electric field as an example) and have them make contact they should cancel each other...

Do something about electromagnetic propultion. Build a linear homopolar motor they are pretty cool and show it to those you are presenting too.

Ok about this length contraction, what is actually happening to the rod that causes it to lose volume (relative to my frame)? If I were to run past the rod at twice its speed after I just watched the rod zoom past me when I was motionless would I see an increase in size?

sorry I should have been more specific. By that last sentence I meant that everything I was speaking about is strictly relative between me and the rod.
