No math. Since we don't know the spoon size, we can assume it's equal to the quantity of a liquid in a glass (of coarse a glass should take this additioal amount).
Now put both into one glass, mix and take half back. Here we are - concentration is equal.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
