Indeed. For someone to present something that can add to the corpus of human knowledge and for it to be later ignored or lost is a great tragedy.The highest accolade for ones thoughts and ideas is for them to be manifested by others and not, in my mind, personal material reward.

A Haematologist. Phlebotomists are trained and instructed by haemotologists to take the samples but they don't analyse them. When I was 16 (mid 70's) it was possible to go in at that age but I don't know the requirements now. My friend went in at HNC. Haematologists are concerned with the study of blood, blood-forming tissues and blood-related disorders. Their work is usually carried out in specialist departments of hospitals where they interpret test results to diagnose blood-based abnormalities. They look at the size, structure, function and amount of different types of blood cells and produce reports and scientific analyses to show their findings. The majority of haematologists work in laboratories in biomedical roles, but others work in blood transfusion centres or in clinical roles where they have direct contact with patients. Working with other clinical professionals is also part of a haematologist’s job. Doctors can also specialise in haematology but this is a very different career route - see hospital doctor for more information. Typical work activities Haematology is a constantly developing specialist area of medicine and provides scope for clinical and laboratory experience. Work activities may involve: receiving and preparing blood samples for analysis; analysing blood samples using computer-aided and manual techniques; reviewing initial data that reveals, for example, white or red blood cell abnormalities; making decisions on further haematological analysis; liaising with other medical professionals to discuss patient treatment plans; cross-matching blood for use in transfusions; investigating the biochemistry of blood clotting; producing quantitative data in the form of reports and providing key information to medical staff about a patient’s condition; assisting colleagues in the interpretation of test results; selecting appropriate techniques for different types of haematological analysis; maintaining accurate and detailed records. http://www.prospects.ac.uk/haematologist_job_description.htm

I am touched in a similar way by Frederick Scott Archer who invented the photographic wet plate process. "Frederick Scott Archer made what was, arguably, one of the most important contributions to the development of photography in the first twenty years of its existence. Having presented his process free to the world, he died six years later in relative poverty and is today, unfortunately, little remembered or honoured for his work and his genius" http://www.samackenna.co.uk/fsa/FSArcher.html

They say: "It's what clocks measure". It's just a parameter.

Back to the Blutak then. If one was really paranoid one could always re-image a virgin copy of the working system every so often...takes about 15 minutes. If I think I might have exposed my system to malware this is what I do...it's a practically bomb-proof method I reckon.

You could disable the appropriate camera device driver in Start > Right-click Computer > Manage > Device Manager. Depending on your version of Windows look through the list for your camera and click to highlight it, then click one of the icons up top that says enable/disable. Windows can't control the device without the driver enabled. You can toggle that enable/disable icon as and when you need.

The notion of the BB being "the beginning" was an interpretive artifact of GR and the state of knowledge at an earlier time which scientists know now is in error...the BB is just one phase in it's evolution. Let's not forget, the lines we draw chronologically at certain temporal points are there for convenience and communication but its development is in fact a seamless continuum stretching back infinitely and moving temporally forward into infinity. If this were false then the principle of conservation of energy must be false, So, to hold true, the energy always existed and will always exist.

The clock ticks on and so does your life. The system is the way it is; outside your control. If you want to do maths you have to work with it as presented now. If you feel you have hit your ceiling in understanding math's take heart in knowing you have done your best. No one can ask more of you than that.

Nothing is an accounting word we use to describe the absence of something, so as an idea it does exist in the mind of a person thinking about it. It's a concept not a thing so it can't exist independently of itself.

Three mods and not one sensible answer to a sensible question...they can have a red one each. I wouldn't put 'jealousy' in this scenario as it relates to coveting or desiring something that someone else has but vain, selfish and intimidating are appropriate.I think. Maybe egocentric as well?

Production of Methanethiol (Methyl Mercaptan)?
StringJunky replied to irisscientist's topic in Organic Chemistry
A probably useless thought but I'll throw it out anyway...at risk of ridicule: would using propane which has Mercaptan in be of any use or would it render the experiment useless? -
Galaxies moving at faster than the speed of light!!
StringJunky replied to esbo's topic in Relativity
You are standing on a rock in space and you can’t feel any acceleration To you, you are standing on a stationary rock. You can’t see anything else around you until you see Alice atop another rock getting bigger and bigger. Alice has exactly the same experience as you, looking at you, from her point of view. Who is moving and who is stationary? Which is the absolute/real/correct frame out of the two frames? Answer: They are both correct. There is no such thing as an absolute frame in the real world. -
Galaxies moving at faster than the speed of light!!
StringJunky replied to esbo's topic in Relativity
Velocity is always relative to something. There is no place that can be said to be absolutely static, therefore, there can be no preferred frame of reference. What time it is from any given frame of reference is a function of the strength of the gravitational field it resides in and the velocity it moves at relative to some other frame. Again, there is no preferred frame. It doesn't matter what clock you use -provided it has sufficient resolution for the test to measure any difference- it will agree with the predictions of Relativity. Very weak compared to gravity...it occurs between superclusters at distances about 200 million light years apart or more. The expansion is a consequence and continuation of the BB...dark energy was postulated to explain the increasing rate of that expansion over time. -
The light is that combined from many stars clustered around the centre that has an inactive super massive black hole, like the Milky Way How bright is the sun? how bright is many suns, such that they appear to be one viewed from a great distance? i think the answer is yes. An active SMBH which is feeding on gas and stars would be even more luminous. An IR picture from the Spitzer space telescope speaks a thousand words: https://en.wikipedia.org/wiki/Galactic_Center

Culturing cyanobacteria - urgent advice please!!
StringJunky replied to jmjabt's topic in Ecology and the Environment
Forgot about notifications. -
What scientists are realising now about General Relativity is that the infinities given by it, with respect to the BB, signals to them that it is losing its applicability as an accurate description as they approach time zero in their studies of it...they need another theory which is as yet not forthcoming.

The OP has not been here for over a year so it is unlikely you will get response. -
Does the colour of light affect growth of plants?
StringJunky replied to Scientist70's topic in Organic Chemistry
It depends which phase of the life cycle the plant is in which colour bands it prefers to to utilise. In the vegetative phase where there is active growth of leaves and stems, yes, it tends to favour the blue end but in the reproductive phase it will bias towards the red end. -
It would actually appear to be arbitrary if I understand this diagram from the Wiki link. I would think there was a decreasing density distribution as you move away from the disk in the vertical plane,: Further reading suggests the spiral arms just contain the youngest stars: The spiral-arm population is the youngest in the disk; it appears to trace the spiral pattern of the Milky Way. This population is concentrated very close to the disk plane, with a scale height of ~100 pc. Representative objects include H I and molecular clouds, H II regions, protostars, stars of types O & B, supergiants and classical cepheids. The metallicity of this population is somewhat higher than that of the Sun (MB81). http://www.ifa.hawaii.edu/~barnes/ast626_95/pcmw.html

Like Pwagen's just said...distant galaxies look look nice and discrete from our observation point but actually measuring from inside one which is, don't forget, truly massive and probably actually quite fuzzy to determine..maybe the observers set an arbitrary boundary to define the furthest extent.

It's about 1000 LY thick. https://en.wikipedia.org/wiki/Milky_Way#Size_and_composition

You know the radius of the wheel. What other measurement can we work out from that and what formula do we need to work it out?

Evolution is the whole enchilada...progression and regression. I am touched by your attachment to my mongrel-bitch native tongue...in reality it is verbal plasticine which moulds and morphs to fit the times. It's that very plasticity that's making it globally viral.
