I'm in the market to get a new toaster. Right now I have none. I was thinking of getting a toaster oven or just the toaster. What kind of toaster do you have and how does it work for you? If you have a toaster oven, do you use that for you toast needs? Is the toaster oven also a convection oven?
Resins that are used in varnishes include amber, dammar, copal, rosin {pine resin}, sandarac, balsam, and others
Think of two people holding a piece of string and vibrating it up and down. You have a little window to look at a part of that string vibrating and you want to work out the momentum of the bit of string you see at any time. When the piece of string is at the maximum and minimum points in its cycle it has zero velocity and zero momentum. Or you can try to measure the velocity as it passes through the mid-point to get the maximum momentum. The point is that examining this little piece of string tells you nothing about the length of the string or the wavelength of the wave moving along it because you don't know where you were looking. You know the momentum but not the position. If you now take away your little window and look at the entire string, well you can now characterise that string in terms of a wavelength, amplitude and a frequency. You can work out which bit of the string you were looking at, but the momentum is now irrelevent for any point because you can describe the motion entirely as a wave. This is basically what the Heisenberg uncertainty principle is about. For a particle to be particularly particle-like, it has to have a momentum and in that case the wave nature is gone because you lose all information about the extent of the wave. For it to be particularly wave-like, you can know the position on that wave, but then the momentum of any bit of the wave is irrelevent. So, for something to be both wave and particle at the same time there has to be some limit that ensures it is both somewhat wave-like and somewhat particle-like.
