But science also includes hypothesis, which are the better ideas without real evidence, but with overwhelming circumstantial evidence. A hypothesis is an educated guess that something is a fact. For instance if I do cook something 1000 times then I could be pretty sure something is fact. But in order for it to become a fact other people have to be able to replicate your experiment and find the same or similar results. For instance I could say that what I need to make a sponge cake is a small list of ingredients. However what if I forgot the necessity for air? What would happen if I mixed a sponge cake in a methane filled space?

Do you need to add a line to the Python code file telling the shell to load the python interpreter? the first line has to be: "#!/bin/python" (no quotes) for bash on Linux but it might be different on your OS It's the path to the .exe file you are using not #!/bin/python it just tends to be installed there on Linux.

Also do you know just how light this thing would have to be? It has to have the lift coefficent of a hummingbird! Yeah but MIT has one the size of a fly so I know it can be done. Yeah but why waste all that electricity unless you're like the NSA and wanna be super high tech and expensive? It would allow for a smaller drone as a battery takes space and adds weight.
-
If we use your definition, then we need to know the facts before science gets off the ground. There is no proof that life exists beyond the earth, so such life's existence cannot be a fact? That is correct. You can believe life will be found beyond earth but that's religion.
-
So is religion being unfairly excluded from the arena of modern thought? Is any mention of gods automatically to be censored from scientific discourse? I think you are misunderstanding science. It focuses on the study of fact. There is no proof god exists thus god cannot be a fact. Religion focuses on belief ie in the absence of fact what do you think happened.

My political defence against "criminal tweets" charge
fiveworlds replied to Peter Dow's topic in Politics
You need to calm down and apologize. You aren't likeable. Your website is crap and makes you look bad. Also what the *** is with your page about looking for a woman who's at least 13 years younger?? With you being what 54 now?? -
lots of rooms and therefore doors, so possibility to get trapped and discharge. Well yeah that would wreck the whole thing. CCTV's coupled with motion detectors or just motion detectors Not if it is small enough and you can interfere with them.
-
What if it is not a house, but project, built from reinforced concrete and somebody will cloze doors and windows when leaving home? No chance a bunker etc could scramble the signal from the drone. There is ways of blocking wireless communication. build and operated, but how long will it survive and remain truly undetected. Well considering you could land the drone somewhere inconspicuous and just record sound or video it depends on what the security procedures are. If for instance a security team checks rooms once a day then you will need to be gone before the check. Wouldn't they be attacked by local birds, for example? This is a problem with most small drones. You could spray the drone with repellants etc and if it is hard to see it is less likely to be a target.
-
Yes but we don't need to recharge we have wireless electricity. So as long as the drone was within the field it will work. The other option is that it recharges battery within the field and then has a range it can fly within for a while and return. Though hummingbird size is a bit big maybe a fly.

it is illegal to collect a sample for DNA testing without the knowledge of the original posessor in the UK You can however kindly ask for a DNA sample should she refuse you may take her to court. Refusal to provide DNA evidence in court is taken badly by the court and may be seen as evidence of her having an affair. Should this prove to be the case you have grounds for divorce on the suspicion that your wife had an affair. Should you not happen to be married you may get off having to pay child support. Though could paternity tests not just be mandatory before a birth cert is issued?? As in the child has to have a paternity test?

...sawmill waste is used in creating of insulation materials
fiveworlds replied to Vladislav Dreko's topic in Engineering
All sawmill waste can be used in building. Woodchips etc can be be used as insulation. The idea being that walls are built with gaps in between then the woodchips and sawdust are poured into the gaps. We have an Eu trial ecovillage near me researching new methods of insulation and house building techniques. They also used the woodchips from the sawmill in a woodchip boiler to heat the houses in the village. They could also have used the same to generate electricity but they decided on wind & solar power. -
Then they are probably still there pipes aren't changed that often. There is also the bsp thread (British standard pipe) used in UK and ireland and Metric iso thread (iso 724) used in mainland europe. Some brewers use npt.

How can two biology students group from different continents work together?
fiveworlds replied to Sven94's topic in Biology
And not sure if you'd know if I was sick from the data I collected about corals. No from your telemetry readings. We can tell heart rate, blood pressure, blood oxygen content, how hot or cold you are etc. We can also tell if your ship has capsized. It might seem far fetched but some biologists get to use nuclear submarines to study under artic ice. So I don't think a budget is involved. -
How can two biology students group from different continents work together?
fiveworlds replied to Sven94's topic in Biology
I am not sure if you misunderstood me or just idk, whatever you're doing. Not sure what that has to do with anything biology related. Let's say you were on a boat studying coral. I would be able to store data you gather on the mainland. Be able to tell if you got sick. Be able to tell where your boat was. Have a fairly reasonable idea of where your boat should be if you sank. Also because data isn't only stored on the ship you don't lose your pictures etc if your equipment gets destroyed. Or let's say you go walking in the woods and get bit by a spider by reading your telemetry you can narrow down what spider could have bit you. Or maybe you go climb a mountain. We could tell how cold you are. Whether you were getting enough oxygen. Where you were on the mountain approximately. How high up the mountain you were. Etc. -
How can two biology students group from different continents work together?
fiveworlds replied to Sven94's topic in Biology
what are ways those two can work together, besides sharing ideas? Are there any ways? Loads of ways. Really depends on how much you can spend You can store data on a central server so everybody can view it. You can boot operating systems from a central server. You can make calls and send messages, videoconferencing etc. You can manage robots, fly drones, take aerial photographs. Track your position via satellite Track your animals via satellite Receive telemetry data about yourself to satellite. So the person on the other side can tell if your heart stopped or you were trapped in a storm. Etc -
Well by genetic testing we could theoretically eliminate a number of gene based illnesses. On the other hand I fear it may lead to parents aborting children who aren't a specific gender.

Light tunnel question
fiveworlds replied to GuyWhoAsksQuestions's topic in Modern and Theoretical Physics
If the mirror can move that will happen. But if it doesn't, where does the momentum go? Same as when you hit a wall. The momentum goes to the particles in the wall which then convert it to other energy forms. Sound and thermal energy for example. I know from cooking that if you beat mixtures too long they heat up. You can also cut a mirror with light :-) -
Light tunnel question
fiveworlds replied to GuyWhoAsksQuestions's topic in Modern and Theoretical Physics
Only if it interacts with something. An individual photon does not lose momentum on its own. Where would it lose it to? It interacts with the surface it is reflecting off. Every time it is reflected it loses a tiny amount of momentum in the collision. Which would lead to the red shifting of the light and then below the visible spectrum. -
Light tunnel question
fiveworlds replied to GuyWhoAsksQuestions's topic in Modern and Theoretical Physics
Assuming the particulate nature of light energy will be lost by the light over time. We know for instance that light will lose momentum. Therefore I would assume that eventually it will reach a critical maximum intensity. -
Clara Tanone - Q4: Do females or males make better nurses?
fiveworlds replied to Clara Tanone's topic in The Lounge
Why is it that males are paid more as nurses despite the field being female dominated? I would imagine that would be because of the discrimination that male nurses get only the ones that really want to work as a nurse would ever put up with it. Comments include. The patients - "hello doctor" And College staff - "how you get on in your pervious year of college?" Oh let's not forget a man is a "male nurse" But a woman is just a "nurse" as if because you're a guy they need to refer to your gender when talking about you. But that doesn't change the fact that the first nursing school was founded in 250BC in India and only taught men. Notable nurses were St. Benedict or Benedict of Nursia - Founder of the Benedictine nursing order Brother Gerard - Founder of the Order of Malta, which is claimed to be the foundation of the knights hospitaller St. Camillus de Lellis - First person to use the symbol of the red cross developer of the first ambulance service and founder of the order of clerics regular or camillians. He also founded a group of health care assistants who would help soldiers on the battlefield friar juan de mena - The first American nurse Jean Henry Dunant - Founder of the international red cross humanitarian movement and winner of the first Nobel prize ever http://www.nobelprize.org/nobel_prizes/peace/laureates/1901/address.html In fact nursing was almost completely male dominated until Florence nightingale and if you look up founder of nursing you will get her name but nursing existed far before her. There exists this reference from 1665 where women 'nurses' were paid by an organization who painted a red cross on the door of a confirmed plague victim. http://www.historylearningsite.co.uk/stuart-england/the-plague-of-1665/ -
It is the Doppler effect. As a side note there is only one imaginary time at the moment which is the day and while a mechanical clock may make mistakes in measuring time the day stays the same. Therefore a satellite in geostationary orbit completes one orbit of the earth in a day. Now if I am in a satellite looking at the earth rotate while moving away from the earth the earth will appear to rotate slower because of the Doppler effect.

How does this tool know how much oxygen can fit into a particular persons blood? It doesn't it measures how much light can pass through your finger. This can be affected by nailpolish or lack of nails. Generally it works on the principle that haemoglobin changes the color of your finger and this affects the ability of light to pass through.
-
Mentos and diet soda. If you choose a clear soda, you could dye it red/orange It is the carbonated water that makes the effect with the mentos. The mentos is a catalyst for the formation of c02 bubbles. The more pressure used in adding carbon to the water the larger the fountain produced.

You are dealing with a signal frequency "carried" by a mere fraction of a volt, which is analog. Incorrect connection would only cause a hum. No it is a small circuit with a ground wire. This means the circuit probably has a transistor which is on the list of things which might blow from reverse polarity wiring.
