Fourier looked at heat flowing through building materials, and his experimental results produced ideas such as thermal conductivity, resistance and the thermal transmission co-efficient or u-value. Read the rest of this entry »
In design work, there is a business side of things that depends on loans and investments. There is also a business side of things where people invest different amounts for different periods of time in helping you — and you might have to figure out their share of things in the future.
