The best thing to do is to not limit yourself to one type of "heaviness." Here's what I recommend, starting with my personal setup. Danelectro Daddy-O overdrive then a Danelectro Fab Tone distortion. This gives you the best of both worlds and these can make real heavy creepy sounds. Another great option for under 200USD is a Electro-Harmonix USA Big Muff Pi Distortion/Sustainer Pedal followed by a Electro-Harmonix Metal Muff. These are VERY popular pedals that a lot of bands you listen to probably use. Remember to use only one pedal at a time and experiment with each one a lot.
Some of my science readings for today… (more to follow, separated by subject) ========== Glasgow scientists predict mass of new particle [www.physorg.com] QCD is a beautifully elegant theory, but far too complicated from a mathematical point of view to be easily computed with. Some experimental results that we believe should follow from QCD, such as quark confinement, haven’t been extracted from it yet. Thus, being able to use QCD to predict the mass of a meson (which is a bound state of a quark and an anti-quark, bound by the force described by QCD) is a major achievement. #qcd #quarks === Going For Exawatts: Building the most powerful laser in the world [www.physorg.com] We all know about Watts (an incandescent light bulb gives off about 100 Watts). Then there’s KiloWatts, MegaWatts, GigaWatts (2.21 GigaWatts anyone?), TeraWatts, PetaWatts, and ExaWatts, each 1000 times bigger than its predecessor. One ExaWatt is a freaking serious amount of power! #lasers #madscience ===…

Toyota says it’s found a fix to its problem of sticky accelerator pedals. That problem has triggered one of the company’s largest recalls, an unprecedented halt in sales and a public relations headache. But amid the avalanche of news reports, some drivers are still scratching their heads over the basics. How does a pedal get “sticky”? And how worried should I be? Here are some answers. Q: How do I know if my car or truck is affected? A: The following eight models in the U.S. are affected by a recall involving faulty gas pedals: the 2009-10 Corolla compact car, the 2009-10 Matrix hatchback, the 2005-10 Avalon full-size sedan, the 2007-10 Camry midsize sedan, the 2010 Highlander crossover, the 2007-10 Tundra pickup, the 2008-10 Sequoia SUV and the 2009-10 RAV4 crossover. Crossovers are SUV-like in size but sit on a car instead of a truck frame. There are some exceptions. Not all models of the Camry, RAV4, Corolla and Highlander are affected by the recall. All of these models produced in…

Toyota’s having a bad week. It is already recalling millions of cars to fix floor mats and gas pedals that have led to unintentional acceleration — a snafu costing the company more than $2 billion. Now it has announced that it will recall about 150,000 of its hybrid vehicles due to problems in the software controlling the anti-lock brake systems in its 2010 Prius and 2010 Lexus HS 250h models. The majority of the recalled cars, 133,000 to be exact, are Priuses. Will this knock Toyota off its green automotive throne? A lot of rivals are looking for the hybrid-maker to mess up. The Prius propelled Toyota to become the green brand — the name everyone thinks of when they hear the word “hybrid” (and the Lexus line brought the concept to luxury cars). But now Nissan, Mitsubishi, BMW, and Ford all have their own eco-friendly cars in the works — not to mention Tesla Motors, Fisker Automotive and Th!nk Global. If Toyota makes too many missteps, its new plug-in Prius, expected in 2013, may not…

It would depend on the bottle cap. Obviously a pop of cap like on a gallon of milk is going to require MUCH less force than a screw on cap made of stiff plastic. You would have to compress the bottle enough to cause the fluid to create enough pressure on the cap to break whatever mechanism is holding it on. Thus bottles with a smaller opening would be easier to pop off P=F/A than bottles (with a similar cap type, like pop off or screw) that have a larger opening.
Draw the free body diagram of the block while it slides down the incline : Since it slides with constance velocity, a = 0
mg acts downwards
Normal reaction, N acts perpendicular to the incline
Friction, f acts up the plane
So N = mg cos 26 …………….(1)
f = uN
and f = mg sin26
or uN = mg sin26………………(2)
From (1) and (2) ;
u = tan26 = 0.5
Now consider the upward motion of the block :
mg acts downwards
N acts perpendicular to the incline
f acts down the plane
Acceleration, a acts down the plane
N = mg cos26
f + mgsin26 = ma
or uN + mg sin26 = ma
or umg cos26 + mg sin26 = ma
or a = ug cos26 + g sin26 = 8.7 m/s^2
Now
Initial velocity, u = 1.75 m/s
a = – 8.7 m/s^2 (minus sign indicates that a and u are in the opposite direction)
Final velocity, v = 0
Use v^2 – u^2 = 2as
s = 17.6 cm
Hope this helps.

I havent watched a single Olympic ice dancing or figure skating event yet and I dont plan on watching one in the future. I do not believe in sports that are judged, let alone sports where the uniform involves feathers and flower pedals.
Here's what you need to solve this problem:
W = KE
KE = .5 * I * w^2
- W is work
- KE is kinetic energy (in this case, all the kinetic energy is in the rotational direction)
- I is moment of inertia
- w is supposed to be omega (angular speed), but you don't see the Greek alphabet on keyboards anymore
Now it's just a plug-n'-chug problem:
4459 = .5 * I * (90)^2
I = 4459 / (.5 * 90^2)
I = 1.01 (rounds up) kg * m^2
CSR Minute Sprint Nextel’s Haiti Relief U of Georgia’s New Susta From: 3BLMedia Sprint Nextel continues to support Haiti relief efforts by donating mobile phones, cell towers, portable generators, and other cell-site equipment to help with communications. In addition, Sprint will credit fees for long-distance calls from the U.S. to Haiti, retroactive from Jan 12th, and continuing to the end of this month. To date, Sprint customers have contributed nearly $5 million dollars through mobile-giving donations. Sprint has also matched the $102,000 given by its employees to the American Red Cross since the earthquake, raising its financial contribution to more than $250,000. Students at the University of Georgia have agreed to pay an extra $3 dollars in student fees to help their university go green. The new fees are expected to generate around $150,000 dollars annually, and will fund a new Office of Sustainability. The Office will coordinate all environmental and sustainability efforts on…
that's fair, since print is not a metric of readership. If newspapers want to be online, why fight biggest online force?
Louis, you know me. I’m just having a joke. (Everyone else: Don’t forget to DM me if you’re interested)
Mr. Gunn, it’s not that I listed a number of huge things you cannot influence in one way or another. We could do a number of things but since the harm was done over the many years, there’s nothing we can do that will give quick results. Small things over many years is the way to go. For example compare this video: with one of the quotes from PZMyers (nothing exceptional for him) “I know my readers like it when the bestiarii take on those animals, the creationists, and they also like the gladiatorial competitions between equals.” Specter on #scio10 was using the same propaganda “you’re dumb” tone. Both have created a number unpersuadable types, because of their attitude. People need to learn, So one thing we can do right now is just to stop supporting certain ways of talking about science.
I think the complaints go back at least a year, but didn’t start getting attention until news of the recalls

From Coulomb's Law
Force exerted on each charge = k Q1 Q2 / r^2
so…. 0.0200 = kQ1 Q2 / 1.5^2
kQ1Q2 = 1.5^2 x 0.0200 = 0.045
new distance = 0.3m, so r^2 = 0.3^2
New force = 0.045 / 0.3^2 = 0.5 Newtons.
Did anything move once you got the apparatus all set up. Did the weight go all over the room and did you have to chase it? If the answer is no, then inertia was in operation. Once in motion, something stays in motion. Once stationary, something stays there.
Equilibrium would more or less impossible without inertia being some sort of factor.
If your instructors have no idea why would anyone else ? It will depend on the cadence, resistance used and the amount of time at all of these different settings.
well ok, again… to whatever degree it solidifies, that’s the degree to which it’s effective as a transmittant, and that’s the degree to which it’s going to cause traction/friction/wear… btw, i’m not 100% on this, that’s just what seems logical, and i’m only pushing the issue because i want to understand it. and going with your eraser analogy – motorize the eraser, and trap the particles at the grinding point within a high-tolerance mechanism, and i think you’ll have problems very soon.
better in June,that is my opinion.
I turned my AC on the other day to cool off my car after it had been sitting in the sun. It spat out pollen and flower pedals.
