Return the item. Did you use Paypal? You probably have recourse there.

Yes. It was too late to edit.

Strong convictions, as well as weak ones are worthless with data to support them. On a science forum, backing up assertions when asked is pretty much obligatory.

This quote seems appropriate: "The average person thinks he is not".

@curiousone So, you think you can bypass the the decades of study that it takes to achieve notability in scientific circles? Science is like any other endeavour... practice, practice, practice. It's my guess that the trmes amateurs have had their ideas 'pinched' on a forum by pro scientistists is vanishingly small. All scientists know that once an idea is 'out there' anyone can use it and they expect/hope it will be used.

What were they thinking?! Mind you, the arming keys to the UK nuclear bombs in the 50's or 60's were kept in a key cupboard in an office on the airbase....

A lump of plutonium from the US WW2 nuclear stockpile. It was to be part of the third bomb dropped on Japan but was used for criticaity experiments instead. Failures in handling the reflector material properly caused brief moments of supercriticality, exposing those near it it to around a 1000 rads of radiation. It eventually killed them.

I think it means whether an allele is dominant or recessive; 'I' is the dominant form and 'i' recessive. There's a table on genotypes in each of these links that might make clearer: https://www2.nau.edu/lrm22/lessons/blood_type/blood_type.html http://blog.cambridgecoaching.com/an-introduction-to-blood-types-genotype-phenotype-inheritance-transfusion-and-more

I think this part is moot after the fact.

Best Charging Strategy for Li-Ion Battery?
StringJunky replied to Markus Hanke's topic in Engineering
Such devices should not be used if they do not have undercharge and overcharge protection. https://www.cassindustries.com/lithium-battery-charge-cutoff-testing/ -
Best Charging Strategy for Li-Ion Battery?
StringJunky replied to Markus Hanke's topic in Engineering
Hi Markus. The Battery University site is the place to look. Practical strategy. Try and keep your battery above 20% before recharging, so use no more than 80% of the battery if possible. Topping up everyday is much kinder than fully discharging until the device switches off. Never leave your battery empty for significant amounts of time....like days. The battery's safe voltage range is 3.2v to 4.2v. A lot of devices will switch off by default at around 3.2v. This saves some residual charge to keep the battery in safe condition. The 'ideal' range is to keep it between 20-90% charged. Most devices don't actually charge to 100%... overcharging is problematic from a safety point of view, If you use the device everyday, charge at the end of the day or after use. Regular discharging to exhaustion really shortens the battery life. Bear in mind practical realities will dictate that you will run it it down now and again to off... you can't avoid it. I get about 2-3 years of everyday use before I think the maximum charge capacity has fallen by half. If battery life matters, don't use quick charging and don't use the device straight after charging, if possible. These are things to aim for but life dictates otherwise sometimes. Avoiding excessive discharge and heat are the main things. To summarize: daily charging is much better for battery life and safety than running flat then charging. Long term device storage when not in use wants to be around 50% filled. -

Are you part of nature and do you have intelligence? -

DIY vaping juice suppliers should have it too as it's a component of vaping liquid.

Kid Philosophy: What is the wisest thing you've heard a child say?
StringJunky replied to MSC's topic in General Philosophy
Smart kid. That reminds me, I read about a chimp that could sign very well and, along the same lines, she called a fridge "open door food". My nephew, who probably 4 or 5, asked me if you went work, you were swapping your life for money? -
Pass a preemptive law, like Putin did recently for if/when he leaves.

Should administrations be allowed to tamper with their overseers
StringJunky replied to StringJunky's topic in Politics
I think the bell has been tolled... and it tolls for her. The resignation of two people will not pass without consequences. What the PM thinks in matters like this doesn't really matter much... once enough people don't like her... the pressure mounts. It seems to be a pattern in politics. -

Yes. I think he will get rid of her anyway, when the penny drops. I get a distinct entitled feeling off her. -
Have a read of this Researchgate discussion: https://www.researchgate.net/post/Thermal_decomposition_of_Sodium_Carbonate Decomposition temperature seems to not be well-defined, due to it being a gradual process over a wide range of temperatures. A figure of 2300K-2400K is mentioned for it's complete decomposition... but note it doesn't actually start there.

Can you envisage any pertinent election cases getting there that might make any difference?
