Hi, Can love be explained by physics? I've been doing some research with no luck. I know there are a few books about however they treat the subject in a spiritual way with no science behind. Then, I've been reading some "theories" about sympathetic vibrations caused by love; oscillations which...

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

A biologist teacher of mine mentioned in one of his lectures that spiders "recheck" the web condition, tensile structure and stickiness properties every now and then when weather conditions are perceived as appropriate (after rain or non windy). I don't know exactly how they fix the lose of glue...

Hi, @AhmedHesham, please do not visit your GP for such things. X-Ray tests and 1 hour GP visit are quiet expensive for the Public Healthcare System no matter which country you're from. Both growth rate and final stature are largely dependent on genetic inheritance, so that, to an extent, a...

The bone structure doesn't contain neurotransmitters itself but the body tissues near the fracture site. Soft tissue refer to the muscles, ligaments, nerves, tendons and blood vessels, joint cartilage, etc. that surround the bone. The level of pain would depend upon where the fracture is...

Thank you. Do you consider the pain scale an objective way to measure pain? As you already pointed out, if you never felt pain before, the pain scale is not reliable.

Hi! Are There other Objective Measures for Pain? Although we haven't yet come up with a cure for pain, we have long effective treatments such as opioids or acupuncture. However, when it comes to being able to evaluate pain based on solely subjective complaint from a patients, without...

Thanks Jim. I have found an abstract summary referring to Chinese Medicine: https://www.ncbi.nlm.nih.gov/pubmed/29105475 St36 - Zu San Li is an acupuncture point located about four-finger space below the patella in the depression on the lateral side of the tibia. It seems that ultrasonic waves...

Hi team of experts, Firstly, I'm not a physicist so apologies for the high level of ignorance. How do ultrosonographic images work? Let's assume I want to observe dynamic changes within a specific area of the body. What type of dynamic changes are detected on those images? Thanks, Jose

Thank you all! I was thinking about your answers and I´m still wandering that if non-militar Satellites use to spread the signal in a great area (TV, Internet, Sat Phone,etc).. so the RUber´s point "also security can become a concern if you are transmitting information intended for a single...

Thanks guys. Clear enough

Hi all, I'm an student of Physics so apologies if I'm just some silly questions here. The higher frequency bands typically give access to wider bandwidths (e.g wifi). Considering that higher frequencies bands (> 30 Ghz) are more susceptible to signal degradation due to ‘rain fade’...

Dear all, I have been searching some scientific basis about the most known -there are others less popular- complementary & alternative medicines listed below: - Aromatherapy - Ayurvedic Medicine - Bach Flowers - Chiropractic - Chromotherapy - Iridiology - Kinesiology - Oligotherapy -...

Thanks Bill. I will check it out.

Hi guys, Just started studying physics hence I obviously have a silly question for you. Why the wave function Ψ (x,y,z) must be square. It seems wave functions themselves have no meaning if they don't have a physical meaning. Thanks a lot in advance, Rodos
