What's your favorite invention and/or discovery in human history and why?

Thx a lot for that reply! He sees a speech therapist/physiotherapist and they often go to a university hospital...especially the one in Antwerp seems to be very able to treat hearing impairment. He's been educated in Spanish and Dutch. A good thing, he's very studious so they often read with him. What I just read : There are currently no FDA-approved treatments for hearing loss that use stem cells, but researchers are conducting clinical trials to test whether stem cell-based therapies for hearing loss are safe and effective in humans. The website ClinicalTrials.gov has the most up-to-date information about the status of these trials; click here for their list of clinical trials which are currently recruiting volunteers. Please direct inquiries about specific clinical trials to the contacts listed on ClinicalTrials.gov, as the HSCI is not enrolling any volunteers in clinical trials. https://hsci.harvard.edu/faq/hearing

The fact that you need a citation for something that obvious says a lot...I don't have a citation because I didn't look for one. Seriously?

Which is what I said. "But we do need our intellect to improve science, technology,... " Science/technology is what will (hopefully) enable us to overcome our drives.

I think it's related to https://en.wikipedia.org/wiki/Maslow's_hierarchy_of_needs. When basic physiological and safety needs are fulfilled then you have time free to spend time on things unrelated to the basic survival needs. I don't have a citation to back up what I said.

Our intellect is the main reason why the world is 'fucked up'. But we do need our intellect to improve science, technology,... for human survival. It's probably correct to say we are the dumbest smart species. Our intellect is IMO our downfall.

I'm pretty sure you are a human. You're basically offering yourself to be a lab monkey?

I think the reason that we often kill for pleasure is because we have the technology to do so and we don't have to battle for space, females/males or food like in the time we were African apes. Since battling for the basic survival traits is not as important as it used to be we have much free time to let our mind wander and do things without a valid reason.

Are there therapies being developed to treat hearing loss? My nephew is 4 years and is deaf in one ear and he hears about 75 % in his other ear. He also has had several ear infections.

Due to global warming the wintertime becomes shorter and will be less severe. Longer/severe wintertime inhibits water vaporization and makes trees ( and other plants) go in 'hibernation'. Global warming messes up this system. Can plants adapt to longer growingperiods with on average less water? Or is global warming to fast to allow a normal evolution?

So then every time a photon interacts with a particle it accelerates? That's odd to say. The Wikipedia definition is then incomplete. Then light can accelerate because it changes direction or because it speeds up? And what when change in direction (refracting) increases velocity? In physics, acceleration is the rate of change of velocity of an object with respect to time. This should be : In physics, acceleration is the rate of change of velocity (-vector) of an object with respect to time.

Can you show me this definition? Light can accelerate , photons can't, they always travel at c.

Why do you think that?

A mirror doesn't accelerate photons. Acceleration is the rate of change of velocity of an object with respect to time.

There is just no force strong enough to accelerate a photon. Photons interact with particles and can loose or gain energy. This changes the speed of light but the photons always move at c. Compton scattering, discovered by Arthur Holly Compton, is the scattering of a photon by a charged particle, usually an electron. It results in a decrease in energy (increase in wavelength) of the photon (which may be an X-ray or gamma ray photon), called the Compton effect. Correct, I think. Certain interacting can completely absorb the kinetic energy of photons. Like in the Photoelectric effect.https://en.wikipedia.org/wiki/Photoelectric_effect

Yes it does, science looks very cool.

Ok. This is a thread about measuring mass of a photon. https://www.scienceforums.net/topic/17347-how-to-measure-the-mass-of-photon/

Ok, but 'zero' implies the complete absence of mass. You can't measure the complete absence of something, you can only calculate or assume it.

This is just my view on this. But it's imo an electron in a superconductor that has the smallest rest mass. In a superconductor there is no electrical resistance, they travel like photons trough vacuum. All or nearly all of its energy is kinetic energy. The rest mass is then imo 'infinitely' small.https://en.wikipedia.org/wiki/Electron_rest_mass#Relationship_to_other_physical_constants

Is there a risk for megatsunamis (they occur when a very large amount of material (like ice) suddenly falls into water) due to the melting of ice on Greenland and Antarctica? I immediately think about the large volcanic area of West-Antarctica. And is there a good chance La Palma will cause a megatsunami?

Mass can be considered to be the kind of energy. A photon has basically only kinetic energy so it doesn't have rest mass.

In January, US and UK researchers will descend on Antarctica to begin their largest joint mission to the continent in more than 70 years. The aim of the five-year project is to understand whether the remote and seemingly unstable Thwaites Glacier will start to collapse in the next few decades. Elephant seals carrying sensors will help researchers to gather ocean data as part of a massive mission to study Antarctica’s Thwaites glacier.https://en.wikipedia.org/wiki/Thwaites_Glacier https://www.nature.com/articles/d41586-018-07847-3

"i]t will still be at least 5-10 years before we consider testing any mosquitoes with gene drive in the wild.” It's a promising technology but it has to develop a lot. First, his team will need to test the gene drive in larger containers, where the mosquitoes can act more naturally, Crisanti tells Wired—swarming to find a mate, for instance. Such details were difficult to mimic in the 20 cubic centimeter cages used in this study. They also need to make sure it's safe for other animals.https://www.the-scientist.com/features/using-gene-drives-to-limit-the-spread-of-malaria-32286 Killing all mosquitoes is not the goal and it's impossible due to many reasons.

It's impossible to kill all mosquitoes. Countries need to work together to kill them all and mosquito eggs can be frozen for many years until they hatch so it's impossible to know if you killed them all. And how are you going to kill all mosquitoes in the arctic, Alaska, Northern Canadian territories , Rusland...

To kill all mosquitoes, countries need to work together. This will never happen since most mosquitoes don't spread Malaria or other life-threatening diseases. In most countries mosquitoes are annoying but don't spread diseases like Malaria. Probably but if animals have less food then they grow smaller. And many animals 'evolved' to hunt/eat a certain kind of animal...they can't just adapt to eat other animals. We should 'hurt' the ecosystem as little as we can.
