The experiment using the NXT arm to pull the mass was a pretty neat demonstration on the basics of power consumption, speed, mass and time.  Like stated in the beginning, the hypothesis and assumptions were all proven true with our experiments, such as more power will equal more acceleration, more mass equals less acceleration, etc.

The bulk of the report should be noted as the outliers and errors that occurred during the experiment and post experiment.  While we did our best to check for faulty numbers during our trials, it is quite possible they were not all accounted for.  This would be the result of either human error during the trial, or machine malfunction (i.e the weight got stuck at the top for an extra second).

I also wish to point out the issue with the scaling on the graphs posted above.  The tools I had at my disposal were Google Documents, which were hard to navigate correctly for the data I had.  Therefore, the scale of min-max on each graph may look different than my lab partner’s….but rest assured our experiments numbers are exactly the dame, as well as the trend of the scatter plot.  Update: For clarity, I chose to replicate my graph with my lab partner, as our results are exactly the same as well as our calculations to reach our conclusions for this lab

The conclusion of this lab should be that such laws of physics that great minds like Sir Isaac Newton formulated prove correct; the more weight needed to pull, the slower the rate of pulling will be….the more force used to pull mass, the faster it will pull….and the time used, the more potential energy should be exerted.

I genuinely enjoyed using a robot to calculate such laws that were discovered well before these inventions were even conceivable!  It goes to show the power of the human mind and how it can define a universal set of laws people of all origins can understand.  One of my favorite examples in the 20th century of this was Alan Turing, who helped decode encrypted messages of the Nazis during ww2 for the British.  He also was the father of the computer, coming up with the mental and physical construct for what evolved into the machine we used today.  In short, I just find this whole concept very cool!

  1. Cellular assays in Hit Characterization

    Cellular assays in Hit Characterization – Cell-based assays assess the efficacy of compounds in a cellular environment, which is crucial to understand compound behaviors in a biological system. Some cellular assays are applied for the identification or quantification of a specific response to an external stimulus, and other assays can measure cellular health such as toxicity effects of cultured cells during or after treatment with various stimuli.
