  1. Re:Many "real" scientists are religious on Stephen Hawking Says Universe Created from Nothing · · Score: 2, Insightful

    it depends what you mean by religious.

    Many scientists believe in some form of god, but don't believe in the traditional sense, in religions themselves.

    Catholicism and the many other flavours of Christianity have always been intolerant of scientific advance, even when many of the people behind those advances were themselves ordained priests or at least in service of the church.
    In the middle ages the catholic church took a backward step from more moderate views and fell back on an Aristotelian descriptions for the universe, not because it was right (many knew it wasn't), but because it could be used as a cudgel to halt the advance the new sciences trying to explain the universe, and the somewhat horrific understanding that the void (vacuum), or nothingness, was a real thing, zero existed. They did not like that one bit.

    Obviously that failed to halt the advance of science, but it wasn't a fast loss. It left us with the foundations of the absurd Christian extremism of today where perfectly intelligent people will deny even the simplest truths that the main catholic church has itself now accepted.

    Islam doesn't get off too lightly either. From them we have the ancient Greek writings and understanding, which they expanded upon, bringing us acceptance of the concept of zero, and enriching our scientific vocabulary with new concepts.

    They expanded a great deal of the understanding they saved from the fall of the ancient world, spread it far and wide, then inexplicably turned their back on science, turning into a religion that frowned on anything that might change the balance of power. Most certainly there were powerful individuals behind that change, and Islam has suffered for centuries as a result, because they, unlike Catholics, were unable to work around the problem, Islamic science is a widespread and accepted movement is effectively dead, and has been for a long time. This saddens me greatly..

    I certainly see nothing in my understanding of 'religion' that tempts me to follow their precepts, although as a scientist I continue to believe in god.

    Just don't go asking me for his phone number..

    I met a kid in his first year (ok, 18 year old) whilst in my second year. He sat down in a supposedly advanced tutorial on robotics for my class and wrote, in less then 20 minutes, a python program that retrieved an image from a robots camera 'eye' and post processed it in the required fashion (to isolate an object in the image by light level analysis).

    sometimes it's useful to write your own. Such as when you need to find a speed increase from somewhere and you have to get elbow deep into the code to find it.

    If the LL code (for example) is someone else's that can be harder. I write most of my own stuff of that nature, because in my work even a few clock cycles shaved off an operation is important.

    If you're creating a product where you need to concern yourself with other issues, like high level customer requirements, then a well tested third party implementation that works right away is beneficial. It all comes down to the context.

    His skill lies in an amazing ability to derive algorithms to solve problems in a very short time. That these usually outperform alternate methods that took longer to develop is what gets him the big money. Large contracts worth many millions have been gained based solely on his database search work. I don't pretend to understand it all, we work in different areas.

    My take on how he is so good is that he spent years studying the issue of algorithm development at uni. Each assignment he did usually was accompanied by in depth diagnostics on algorithm performance, far beyond the course requirements. He cost me an A++ once when working on EAs because his work was so much better than mine I was reduced to A+.

    It's a nieve point anyway. Computers are not 'old enough' for that. The only things that can are languages running on VM or interpreter.

    I do agree with you, but language is important. You need a decent working knowledge of some mainstream ones in order to be employable, I was trying to take account of this need.

    I can't stand sitting down and coding as a sole means of working. I prefer to go for long walks to work on the problems I solve, then spend some whiteboard time refining it. Only at that point do I instantiate in code.

    You remind me of something a lecturer said in my second year 'You can use any language you like except for Visual Basic'. He'd been told to restrict students to the one language, and he threw that out of the window. We also had a wide spread of languages used for that assignment.

    Self study.

    Of the people I knew who did well, those who self studied alongside their normal course did things like website design, search algorithms, micro kernel design, robotics and advanced study in certain languages (lisp, c++, C, Object Pascal, assembler), everyone I knew did the last thing, but the languages varied.

    You can pass and get a 2.1 or 2.2 easily just by following the course guidelines. I got my phd offer not by doing this, but by cramming every day (almost every day, have a blowout night at the weekend, you've got to have some fun time) with additional study. I exceeded the requirements of every assignment (I wasn't alone in doing this), and studied around every topic taught. The result was a lot of very interesting phd offers when I graduated, it rocked. I was tired a lot, I will admit, but the benefit was vast, I was so far ahead of the students who just followed the course that I actually tutored some.

    Don't assume I'm that clever though, I sweated blood sometimes trying to get assignments done early, and the extra learning was oft times very difficult. Every evening spent on it was one well spent however.

    Most of the people I know personally who did this are now in great jobs, one heading towards millionaire status at 25. In his case he worked like a dog, even more than I did. You wouldn't beleive what he was capable of on graduation.

    So work hard, and study around the subjects.

    Over the last six years I've been increasingly worried by the falling level of ability in CS students.

    I've encountered CS students recently who in their third year are unable to do such basic things as understand memory allocation. As for algorithm design? Well that's simply unknown by the majority. That scares the shit out of me.

    The Mantra is 'don't re-invent the wheel'. This is used as an excuse for students taking off the shelf components for assignments (sorting classes for java being used for sorting assignments for example), or being given virtually complete assignments by lecturers and being walked slowly through the assignment to the point where little or no original thinking is required.

    Now it is true that re-inventing the wheel is a bad move at times. However whilst studying for their qualification, they should learn how to build the wheel in the first place.

    Back to the memory allocation point. I currently know of no final year students with a decent understanding of this topic, and yet it is the main cause of security problems in code. They should at least have a working knowledge.

    The ephasis is more and more on using languages designed to try and remove the main problems in code, but who writes these languages? It sure isn't the people who are only taught to use them, not create them.

    The normal course of action is to blame Java, since it has led to a simplistic approach to CS assignments. I'd love to blame it, I ferkin hate the language, but that isn't the root cause.

    Computer science is a hard topic that they are trying to make simpler to encourage more students. This has the result that CS students are graduating with ever reducing levels of ability, so people no longer see it as a worthwhile topic. Nowadays a CS student who wants to do really well has to work on independent study entirely apart from the course they are attending, and has also to face the unpleasant reality that their education as provided by the university is so poor that they may face years of further study to gain a useful level of ability.

    Post graduate study can reduce this problem, but there are fewer post grads too, and often it is funding, not interest in a topic, that guides the selection of a course.
