Wave like behaviour Sorry if this is a repeat but I'm curious if wavelength $\lambda=h/p$ then does that imply that we would be able to observe the wavelike properties of a very still object? For example an average human weighing $65\ \mathrm{kg}$ travelling at $10^{-28}\ \mathrm{m/s}$ should have a detectable wavelength of $101.94\ \mathrm{nm}$ so would they exhibit wavelike behaviour? 
 A: Yes, any object will have a wave-like nature, this is very interesting and perfectly real. The thing and the reason why we don't see the macroscopic world around us acts a little like the quantum world is that nothing as a small enough momentum. $h$ you know is very very small about $10^{-33} kg \space m^2 /s$ so to be able to observe this wave-like nature of this it should have a momentum which ridiculously small. Nothing has small enough velocity to make the objects exhibit this nature, because their masses is way bigger than anything in the quantum world and trying to have as you said a velocity of about $10^{-28} m/s$ would be almost impossible because everything moves way faster and everything interacts with one another. For example right know you can be completely still and still move in space at an incrdible velocity auroud the sun and even more aroud the galaxy. But the answer to your question is yes, everything posseses its wave-like nature. So we are little thinking waves, really little (with an incredibly small wave-lenght). 
For technicality the wavelength of matter is given by the De Broglie wavelength, $\lambda$ where:
$$\lambda=\frac{h}{p}$$
where $p$ is the momentum: for objects moving much slower than the speed of light in the current context, $p=mv$ where $m$ is rest mass and $v$ is the velocity of the matter.
