It was the same kind of logic question. You missed a key word in your quote. I think it said “If you study hard enough you _can_ pass the exam”. It was there to make it clear that studying hard is not a guarantee for passing the test, and therefore can’t be used as the certain reason for failure.
I’ve tried leaving kindle but keep coming back because of how well it syncs side-loaded (via email) epub reading progress between the physical reader and the kindle app on my iPhone.
I recently got a Boox Palma, which I love, but the Android Kindle app can’t display time remaining in a chapter for emailed epubs. I find this very surprising, considering both the kindle hardware readers and iPhone kindle app have no problem doing this. Sharing this story in case someone else has run into this and identified a solution.
I recently got a Palma as well, but just had the display randomly break in my soft coat pocket (note screen and touch are totally fine, just the eink). I would recommend other people avoid them due to this random breakage.
In the context of the reserach it's helpful to know they were all psychoanalysts. They focus on the human needs we acheive through work that are overlooked from the functional or material needs/outcomes of work.
In a modern context attend means would be more in line with EQ. Being about to sense, contain or facilitate someone scratching the itch of a need. It could be simply to help clarify, to hear, to reassure, to encourage, etc. All situationally specific based on the individuals in the group.
> Then I realized that a 5V supply will always be 5V in normal operation and ohms law means the current varies.
This is a great observation. I've often thought that teaching Ohms law as I=V/R would lead to less confusion. Similarly, in intro physics why is mass acceleration introduced as f=ma? Wouldn't a=f/m have a clearer meaning?
I agree, that’s my preferred form as well. That’s because Ohm’s law is an empirical law, which states that current is proportional to voltage. It’s the definition of resistance, and it’s not always valid.
It becomes infinitely more clear and simple to understand when you stop thinking in terms of "A equals F divided by M" and think of it as "A equals the ratio of F to M".
It also is infinitely more clear and simple to understand when you correctly realize that "F equals M times A" instead. I assume this was just an accidental transposition and you're not actually a crackpot. :)
A Watt is an SI unit defined as 1 joule/second, and is used for measure rate of energy usage/generation. So this system generates up to 100 joules/second, and can output up to 150 joules/second (until the stored energy is consumed).
Why is the world's energy production a constant value from 2010 to 2040? Surely we produce more energy today than we did 30 years ago. Is this just a chart scale issue?
As pointed out by JosephRedfern, the production line is not exactly flat but has a very slight grade (http://i.imgur.com/oTUC2Nf.jpg). This means they postulate an increase in production.
