Human body Definition and 133 Threads

Hi I need all the bonding frequencies for all the elements in the human body, IE: carbon-carbon single bond frequency of 1300 cm - 1. It is very important to have the single, double and triple bonds because I am doing something that will require them all. It would also be helpful if someone...

I'm trying to find the moment of inertia of a human body with (say) the upper arm at angle alpha to the torso and the lower arm at another angle beta, where beta is the angle between the lower and upper arms. I model the torso as a cylinder of radius R, mass M and the parts of the arm as...

I want to know the answers to the following: 1. What REALLY happens to the naked human body in the void of space (the areas far between galaxies, where nothing really exists)? 2. Can humans evolve and adapt to survive in space? 3. (Adding on to the previous) can we slowly depressurize (akin to...

The human body is made up of mostly oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Less than 1% is sulfur, potassium, sodium, chlorine, and magnesium. If a human body was teleported to the surface of the sun, what would happen to these elements? Which ones would cease to exist...

I recently read that there is enough hydrogen in the human body to lift 195 lbs off the ground. I know this sounds super-silly but if we ever develop nanites; could they manipulate the hydrogen and allow us to float?

I'm interested in chemistry but it's all new for me and I'm just starting out. I tried to do some calculations but got stuck... I was wondering, for example a supplement has the following values: Molar mass: 306.247 g mol-1 Tmax 2-4 hours Cmax 363.3 ng / ml Half life: 11.21 hours How do...

I'm sure this is a strange question, but I am really curious as to whether the human body can produce electromagnetic pulses. And particularly, whether an orgasm is a type of EMP. Wikipedia says an orgasm is "a sudden discharge of accumulated sexual excitement". So is this discharge of...

Summary:: Looking for a certain degree program What kind of degree would be best if I really wanted to get into studying energy within and around the human body and interactions of it between electronic signals and things like that? I am really starting to believe that our understanding of...

Back in grade 10..,.( Oh my that was awhile back 😀 ) our electronics teacher passed around a multimeter and everyone measured their resistance ( a lead held in each hand, Fluke was set on infinite ). All in the class measured between 700K and 800K approx. All except me that is. I measured 1.4M...

I was in doubt if this is the right chapter to place this thread, but it seems there are many talents just here. "we were observing from a decent distance through optics. The weather was frosty, clear, calm. When хххххх appeared from under the arch of the house (he was хххххххх to walk to the...

Apologies if this is in the wrong section as it isn't particularly medical in nature despite it being about the body. I am currently conducting a rapid review with outcomes of knee muscle strength. This is measured by biodex dynamometry, which assesses numerous values including Peak moment...

Can we use the electricity from the muscle to power an engine (like a prosthesis)?

Hi, Does the brain control the physical growth of a human baby? I think if, for some unfortunate reason, the brain is absent, the growth would still take place normally but more like a vegetable. I don't think if the brain is absent, one can even blink the eye or move a finger. But the...

I was researching what the total electrical resistance of the human body was and got some quite far ranging values. It seems to range from 1, OOO to 1OO,OOO ohms. Some quite elaborate ways of testing it too. Then I thought I'd just get the old multimeter out. I have two and both measured about...

Apologies for the noob question. The frequency of the human body can be calculated based on weins law as follows: Wavelength = 0.002898/310 = 0.00000934838 m Plugging this into the equation λν = c we get frequency = 299792458 / 0.00000934838 = 32069 Ghz Elsewhere, I see that the resonant...

So I discover that a human body can affect a radio receiver. When I get close to a receiver, the radio produces buzz sound, which means that the radio signal is disturbed. However when I touch the plastic case of the receiver, the receive becomes normal. This phenomenon does not happen every...

I am a high school science teacher working on arts integration for thirty years in schools where many students have academic skills below grade level. I am looking for feedback.

https://www.sciencedirect.com/science/article/pii/S0370269320301040#br0210 I need to give this more thought, but the ballistics section is pretty good, and I think their basic dE/dx argument is sound: If a collision at a ballistic rate transfers about the same kinetic energy to the human body...

Hi I would like to know the facts about this

Hi lads, I couldn't find this info on Google... Are the Heart and Brain the only organs which physiological functions are based on electrical impulses? What happens if we apply electrical current through other organs? Thanks

If this is a valid enough definition of a heat engine: All heat engines transfer heat energy from higher to lower temperatures, and do work in the process. ... then is the human body a heat engine?

Hello Everyone, Sunlight is composed of UV, visible and infrared (IR) over a wavelength range from ~290nm to ~2500nm. When we are exposed to sunlight and feel hot, is it because of the absorption of energy at the visible wavelengths and FIR, i.e . infrared wavelength much larger than 2500nm? I...

During these days, I have asked my mother: What is better/worse for the human body: salt or sugar? Both of these substances are quite dangerous in high amounts, but which one is worse? Salt was used in food preservation, with its abilities (Which abilities? I have never understood this...) and...

In my Thermodynamics course, we recently learned about the saturation pressure and saturation temperature of different substances -mainly water. As you know, the saturation temperature at which a substance begins to boil is specific to a fixed saturation pressure. Water only boils at 100...

Hello everyone, I know that the any object, human body included, when the vertical line from its center of mass to the floor falls outside the base of support, topples under the influence of gravity: the force of gravity produces a nonzero torque that rotates the body. Is the human body able to...

What types of light are able to pass through the human body without causing damage to tissue or individual cells? Are there any truly safe alternatives to x-rays that could allow doctors to see internal body parts but not cause damage from extended exposure?

Hello, It is well known that the atmospheric air pressure is significantly strong but our body does not get crushed by it because and equal pressure pushes from the inside our body. That said, does it mean that air can exist and be diffused inside solid organs like the lungs, our heart, etc...

Hello, I've been watching too much anime. I know that isn't the best way to ask a question scientific in nature, but visualizing bizarre situations is one of the best ways to come up with interesting questions. Anyways, in order to break a rock by compressing it with your hands, you would need...

To be more precise, which nano particles are being used or can be used to deliver tuberculosis drugs in the human body?

I have been thinking, looking for an answer. It is known to me that drinking pure H2O is bad for the body, reason is it saps all of the minerals from the body since it does not contain any. I have been thinking, if I take salt water from a certain sea, put it in a container and boil the water...

Hey all, *this is my first post on this forum* I've read a lot about the different ways of artificial gravity on this forum, and we've discussed everything from realistic ideas that can be accomplished with today's tech, all the way to fictitious situations in sci fi books. BASICALLY, I would...

Homework Statement The intial step in the digestion of milk in Humans is carried out by which of the following enzymes? A) lipase B) trypsin C) rennin (No, not renin) D) pepsin Homework Equations Casein is converted to Paracasein by rennin and then paracasein along with calcium is acted upon...

I am looking for resources on the physical properties of the various components that make up the human body. As an example of what I am looking for; If we look at the finger, we know it has bones, skins, nails, blood etc. What are the various physical properties of these different parts...

I read posts from a few years ago regarding measuring frequencies in the human body. I am wondering if there are any new developments. What devices can measure frequency? Thanks!

Hi all, Would anyone be able to let me know what the average frequency is for the human body? Also, what is the average frequency of a home? What would be considered abnormal? According to the Ofcom UK Frequency Allocation Table it notes different frequency uses e.g. a frequency of 1,600...

Homework Statement The number density of 1H nuclei in the body is roughly 600 times greater than that of 13C nuclei. By what factor is the magnetisation M0 of 1H greater than 13C in the same external magnetic field? Homework Equations 3. The Attempt at a Solution [/B] Surely it can't be as...

A curious question that's come to my mind, as I'm doing a little research for game development, aiming for realism here. Assume you have a human corpse, not doused in any special kind of fuel, but wearing cotton/polyester clothing. And you set it alight, to slowly burn over time. I've heard of...

I understand that this will vary from human to human, but how much weight is exerted, in total, on the average adult human body. It would be very much appreciated if the calculations can be shown. Thanks!

Ham goes bad if you leave it there for a few days but why doesn't human body goes bad if you leave it there for a few days and when the person is alive?

Is the Human body capable of creating any type of frequency ? Of course vocally but beyond that ... . What devices are in existence that can measure or see frequencies of living things ? Have there been experiments with documented results that shows frequencies created by the human body ?

One of my favorite dreams is to be a doctor but I don't know where to start. I love studying the human body and do experiments to my own body (but not to the point where my experiments hurt). What course do I need to take and how do I prepare for it?

Why do some people sneeze on exposure to light?

The astronauts who were traveling to the space. in what way their health were affected? During the rocket launch the spacecraft should travel greater than the Earth's escape speed. Is this speed affect the astronaut? And tell me which is the maximum speed that our human body can bear?

I am making home automation model and I have few sensors installed to sense some changes in the environment to detect any changes. So these sensors provide me data , but I want to know what changes does Human body exerts on the environment it enters, so that I can install those sensors which...

It is said that around 90% of the cells in a human body are symbiotic bacteria living thanks to us. When we die, do most of them also die? Or do they manage to survive without us and find a new 'home human'? And opposite, when and how do we get all those bacteria after conception? Do we get...

If our body temperature falls below 30 degrees C or so, it stops functioning properly and we die. 30 C seems still a rather warm temperature for normal chemical reactions to be able to occur, and in most environmental conditions inhabited by men it still represents a temperature gradient...

Greetings. Well I do not have enough time to pose all of my questions and ideas I can get this thread started off. So let's get right into it. The teeth of a Beaver incorporate a comparatively high percentage of iron in their construction, making them very strong and orange hued. (Also made to...

I was lately interested in learning how the human body weight changes through out the day. Like, how much weight (may be in just 10s of grams) is lost during sleeping, after bathing, after workout and like that. For that I would require a highly precise scale. But most commercially available...

Hello guys, I read some articles recently about how touchscreens work by using the capacitance in human bodies. I'v seen the human body capacitance is quoted at around 100pf, is it the same when the human body is floating in mid-air, as if it is standing on the ground? My goal is to detect...
