  1. Hi Everyone If you are asked to assign the colours red, yellow and Blue (listed in no particular order) to the shapes triangle, square and circle (listed in no particular order), then which colour do you assign to which shape? You may at this point wish to pause reading this post while you consider your own personal answer to this question. I personally, strongly believe that there is no "correct" answer to this question and it is purely subjective. However, the teachers at the Bauhaus believed that the following correlations are the correct correlations: Triangle = Yellow Square = Red Circle = Blue My personal answer (which I came up with before knowing the "correct" Bauhaus answer) is as follows: Triangle = Red (sharpest shape, sharpest colour) Circle = Yellow (like the Sun) Square = Blue (boring shape, boring colour) Would the fact that my answer is different to the Bauhaus answer make me a bad Bauhaus student? Does anyone here know of any neurological, psychological or any other scientific reasons why the Bauhaus answer is the "correct" answer? Thank you very much. Kind regards Tim
  2. Hi everyone. If the entire Amazon rainforest burns down, will we all find it noticeably harder to breath? Will it be like we are all at a higher altitude?
  3. Hi Phi Thank you very much for your reply. Correct me if I am wrong but what you generally seem to be saying is that salt has a tendency to dehydrate you. Am I correct? Is it perhaps the case that there are some circumstances when salt dehydrates you and other circumstances when salt aids hydration?
  4. Hi Phi Thank you very much for your reply. Unfortunately, I can't find the original article I read but I have just found another one which says something similar. It basically states that as a result of osmosis, extra salt in your blood sucks water out of your cells. The other article went on to say that you pee out the water that has been sucked out of your cells. You can see the article I have just found here: https://sciencing.com/drinking-salt-water-dehydrate-you-6454208.html
  5. Hi Everyone There is something which confuses me. I have read that if you add salt to water, it helps with hydration. I have also read that adding salt to water makes you pee more. Wouldn't this cause dehydration? How can both of these statements be true? I would be very grateful to anyone who can remove my confusion about the relationship between salt and hydration. Thank you very much. Kind regards Tim
  6. What if i want to be as close to 100% as i can get that none of my data will be corrupted? Surely If I just backup to one other drive, I am still a bit vulnerable?
  7. Hi Koti Thank you very much. Why do you think that RAIDs are useless in home environments?
  8. Hi Koti Thank you very much indeed for all your help. I have just one more question: If I was to create a RAID 1 array with four hard drives and I was to use the btrfs file system, do you think that this would be pretty bulletproof against data corruption or can you see any potential flaws in this set-up?
  9. Hi Koti Thank you. Do you know if there are any circumstances whereby an error (such as a single bit flip) can develop on a hard drive without the hard drive detecting it? Or do all of the latest hard drives use mechanisms such as checksums to detect errors?
  10. Hi Koti Thank you very much for your reply. I was not actually meaning the other way round. Can RAID 1 systems detect all types of errors that can occur on a disk or are there some types of data error it can't detect and therefore wrongly think it is the correct data?
  11. Hi Koti You seem to be implying that the RAID 1 system can always detect if it is attempting to read data from a bad sector and if this is the case, it will get the data it was attempting to get from the other disk instead. Am I correct?
  12. Hi Koti Thank you very much for your reply. It has just occurred to me that a hard drive in a RAID 1 array can possibly remain "functional" in the array even when it has some bad sectors and that file corruption due to bad sectors can spread when RAID 1 arrays are rebuilding after a hard drive has been replaced. Is this true?
  13. Hi Everyone I have read that RAID 1 arrays work in such a way that when a file is copied to a RAID 1 array, it is copied to all of the hard drives in the array simultaneously. In other words, it is not copied to just one of the hard drives and then copied from this hard drive to the others. I have also read that if a bad sector occurs on one hard drive in the array, the resulting data corruption can spread to the other drives. What I don't understand is how both of the above statements can be true at the same time because how can the corruption spread if data is not being copied between the hard drives in the array? Thank you very much. Kind regards Tim
  14. Hi Swansont Thank you very much indeed for all your help. I will have a look at the Khan videos.
  15. Hi Swansont If this is not the place where non-experts such as myself can communicate with experts such as you in order to explore ideas such as mine to find out how plausible they are then can you point me to another forum on the Internet which serves this purpose? The fact is that, because of events in my life beyond my control, I do not have any direct access to academic expertise. Such access is the privilege of the few. Without the support of academic expertise, it is very difficult for me to develop my ideas and to verify that they make sense to the scientific community. I find this deeply frustrating because I am insatiably curious about this sort of thing. Just watching scientific documentaries and reading science articles in magazines and on the Internet is not enough for me. Sometimes when I am listening to the scientists speaking on these documentaries or when I am reading what they have said in the articles, I often want to ask them various questions. Sometimes I have sent them very polite emails asking them the questions I wanted to ask them but the vast majority of the time, I have never received a reply. Can you understand my frustration? I would, however, like to point out that I am actually deeply appreciative and grateful for the time that you and your colleges on this forum have all given me with this with your expertise. Thank you very much indeed for this.
