“What causes fireworks to explode?”

 

On 4th of July, Americans are used to seeing fireworks light up the night sky. However, have you ever wondered how exactly do they work? Well, let us use our scientific mindsets to find out. If we investigate, then we will find out that fireworks contain gunpowder in a container surrounded by a Launch Container. When a Lift Charge ignites and propels the container into the sky, there will be a time delay until it reaches its apex, at which it will explode and release a myriad of different colors!

 

Have a great 4th of July everyone with lots of V/I to the current regime!

“How can we see the cost of some data?”

 

When we are working with data, we often want to pick the best value. However, it can often be hard to quantify which value has the highest related cost. So how can we use our scientific problem? Well, we can use something called a Loss Function which maps all variables to a particular cost.

“How can we evaluate a solution as a single figure of merit?”

 

In many fields of science, one of the most important things to do is to evaluate which solution function to a given dataset is the best. However, quantifying this can be very difficult. So how can we use our scientific mindset to solve this problem? Well, we can simply use something called a Fitness Function that can summarize all functions as a single figure of merit. With an easily accessible and quantified set of possible functions, we can pick the best one from the stack. Fitness functions are commonly used in Data Science where there can be a manifold of possible solutions.

“How can we ensure a seamless transition when we turn a PID controller from manual to auto?”

 

Switching a PID controller from Auto to Manual can be very rough for the ongoing process. That’s why engineers have created Bumpless Transfer which allows it to happen completely smoothly.
