    Why do you send me emails to come to the site if you will not give me permission to post? When people seem to know the answers and do not want to give them for homework reasons that is one thing but a question that even people who so plainly know what is going on do not understand how to answer...

    What are the Limitations of Machine Learning in Causal Analysis?

    It seems to me that we don't even know how a human being thinks. How his memories are stored and in what order. Humans have trillions of possible neural connections and if you were to get a couple of hundred thousand in AI you'd be a great deal better than any AI presently is. And remember - you...

    What are the Limitations of Machine Learning in Causal Analysis?

    OK, went to the people who know the real stuff and it seems like the settling time to get an accuracy to one part in one thousand would be 100 times that maximum speed of the circuits. This sort of kills that idea since it would make about a millisecond to get accuracy in a common op-amp. Now...

    Why is my tax refund lower this year than last year?

    I don't understand - what do you need to guess at? If you want to change to a different deduction you may. Otherwise just leave it as they set it. Even if you end up owing money unless you had a windfall of some sort you would owe very little. My brother retired from a civil service job last...

    What are the Limitations of Machine Learning in Causal Analysis?

    Digital logic is so fast because it only has two states. Analog has a theoretical infinite number of states though due to actual accuracy it has more to do with settling time. And this is a great deal slower. Whether the increased accuracy of a smaller number of "bits" is worth it hasn't been...

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    Pardon me, it is a German manufacturer that is pretty well known for accuracy. But it never occurred to me before this discussion that the accuracy is offset by the response time.

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    The rough downhill ends and there was a couple of bike lengths before it got onto the smooth pavement. This is what was throwing me - there didn't seem to be any easy answers.

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    It Is a VDO so It is pretty insensitive to the magnetic field distance. Having actually written this out now and looked at it with the knowledge that conservation of momentum is a law that simply can't be broken that has to be the only answer. I also think that I've seen a delay off of stop...

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    The change from the descent to the flats isn't that abrupt.

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    Well, remember that I had instrumentation. While the grade is a somewhat coarse means of grade measurement the actual changes in altitude are pretty accurate. I have done rides over and over with over 3300 feet of climbing and the total climbing hasn't varied more than about 50 feet and that is...

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    The downhill is about 4% and I enter it at about 15 mph and coast down and at the bottom where the smooth part was, I was doing about 20. Then my speed would increase to 22. This was particularly odd because at that speed there is enough aerodynamic drag that you sure wouldn't expect that to be...

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    Well, I most definitely do not agree with your assessment of being able to tell grades less than 2%. And this isn't just the gradient measurement. It shows perhaps a change in altitude of a meter. The quantization of an altimeter has to do with the change in altitude over several meters and the...

    Why did my bicycle speed increase on smooth pavement while coasting downhill?

    Something occurred to me that doesn't seem to make any sense to the way I understand physics. Perhaps someone can explain it. Riding a bicycle on a descending road on very rough pavement and coasting I came to a flat and they had repaved it and it was perfectly smooth. My understanding of...

    What are the Limitations of Machine Learning in Causal Analysis?

    Let me offer some opinions as someone that used AI early in the game. The human brain is perhaps the closest thing to infinite we've ever found. AI runs on a computer which isn't even as brilliant as a lizard. There are arguments among authorities of whether a brain works using binary logic or...

    How is mathematics related to creativity?

    I had several jobs in which physicists presented me with mathematical problems to build into electronics designs or program into computer code. The problem was that their analysis of the problems was incomplete, or in one case, totally incorrect. I had to analyze and work the entire problems out...
