Light also penetrates the skin few mm or more (hold a flashlight to you finger) why aren't we studying similar effects with artificial lights which have much more radiative power? >Maybe claim #3. Plenty of papers on that I can find

Yes I almost thought it was an April fools joke article like dihydrogen oxide dangers.

Obviously if you have read their criticism its gets much further than "non-ionizing can't harm", its a criticism of the methods use to analyze data from other studies in cherry picking fashion, they did no actual testing them

>There are other mechanisms by which non-ionizing radiation can induce cancers, such as the one I've described. Link please, there are no proven mechanisms such as you describe I am aware of. Your only link points to sun exposure an

Such aggressive ad hominem attacks are not warranted, you want to dispute my position then have some class, its ok if you don't know how radio receivers work.

by SigmundA 5y ago
Digital receivers which are in cellphones are most certainly based on A/D convertors which is what you originally referenced. All captured antenna energy is dissipated as heat through resistance in order to extract useful information a

No antenna is a perfect point omni emitter, the weird non spherical shapes like doughnuts is the antennas gain, almost are antennas are somewhat directional, the shape is a plot of the measured radiation around the antenna. You take advanta

No the ADC use resistors to measure voltage, resistors turn electric energy into thermal energy, they literally use how much time it takes to dissipate electricity as heat to measure voltage. I know someone who needs to read up on antennas

Really so cellphones are actually microwave lasers, cool!

Cellphone transmitters are not coherent, they are like LED christmas decorations except lower power.

Post a link, please?

There is absolutely no proof that cellphone levels of power induce ion motion as you have described, I can find some theoretical work at much higher power levels that proposes it as a mechanism but is not definitive. You need to do better t

How is alternating current steady when varies in magnitude? There is no current flowing on a zero crossing, there is a reason AC and radio use RMS current, are you sure you know what your talking about? Incidentally the ADC's that samp

Posting no backup to your claims is not helping your argument, please enlighten my ignorance, I thought for sure we cooked food with microwave ovens.

by SigmundA 5y ago
Radiowaves are AC by nature they are not "Steady current". You need to provide at least something backing up this extraordinary claim. Are you claiming a heating effect or something else?

by SigmundA 5y ago
You need to provide some evidence of new biological activity from microwaves to revolutionize our physical understanding, the burden is on you not me.

Your phone isn't typically on full transmit power in your shirt, this can been by the difference between talk time and standby time on any phone.

by SigmundA 5y ago
The only known effect of microwaves is heating which is purely based on power hence why we cook food with them. They are also good at transmitting information quickly so we also use them at 4 orders of magnitude lower power in your cellphon

UVBA/UVB are near ionizing, UVB is right at the transition point, they have enough energy to cause photochemical reactions that damage DNA but not enough to cause full ionization. The key concept is that it is based on the energy of th

Careful you might have to explain inverse-square law.

by SigmundA 5y ago
Which is why microwaves are known to be safe because they are lower frequency than even light so the only known biological effect is heating which is purely a function of watts per kg exposure.

They get a lot more from the sun and some of its is actually ionizing and causes cancer.

No unfortunately PG does not have clustered indexes much to my dismay.

Memory kind of blurs together, but probably was doing larger programs with the tape, 5-9 minutes for a 16kb program [1], felt like forever. Also might be mixed with memories of the C64 cassette which is 30 minutes per 100kb per side [2] so

It is such a common access pattern that many database engines always have a clustered index (MySql - InnoDB, Sqlite) whether you use them directly or not. I like having a choice as there is in Sql Server or Oracle, but for many use cases it
