    B Predicting frequency of Earthlike planets and systems

    Each new report of a confirmed exoplanet adds to the database of knowledge. For obvious reasons, our confirmations seem to stack up in the areas we are currently best able to detect. eg.: Large bodies: Jupiter-sized down to Sub-Neptune-sized, with a smattering of super-Earths. Nape-of-star...

    Can I save anything in my greenhouse from frost damage?

    Funny, where we have moved to is in the middle of the Niagara Benchlands, there have got to be a score of vinyards and fruit orchards within a half hour drive - smudge pots are ubiquitous. Unfortunately, for my purposes, using smudge pots indoors is contra-indicated.

    Can I save anything in my greenhouse from frost damage?

    By the way, in case it looks like I'm making a big deal out of an otherwise perfectly understandable and harmless rookie mistake, the reason is because not all these plants were new. Some of them were kept in my wife's office under her auspices for decades, after having been bequeathed to her...

    Seeing a mobile phone screen remotely

    Try Goggling "screen sharing a mobile phone". There are a lot of ways it can be done but will depend on the particular technology. But for a quick, low-tech solution, have him build a makeshift stand (like, say a stack of books, or a steady beer belly) and set his phone in front of the computer...

    B Graphing trip efficiency - distance over time

    I'm terribly sorry for the confusion. I have been indeed been unclear. I pulled a bait & switch and did not inform you adequately. The graph in post 1 - while not literally based on recorded data - is pretty accurately based on real world experience - including stoplights. A short stint at...

    B Graphing trip efficiency - distance over time

    Where are you drawing this from? The trip only takes 45 minutes. I am converting all averge speeds to km/h. So the 60km trip takes 45 minutes, or 4/3rds of 60 = 80 At the 42 km-to-go mark, it will take 27 mins., which converts to 93.

    B Graphing trip efficiency - distance over time

    T+60? Or t+45? It's a 45 minute drive.

    No. Jealousy involves the threat of loss; it doesn't have to a relationship. Envy is “the painful feeling of wanting what someone else has, like attributes or possessions.” If you're jealous, you feel “threatened, protective, or fearful of losing one's position or situation to someone else.”...

    Right. But it's all relative and subjective. An eleven year old who's lost a beloved parent in a messy divorce could certainly go a round with a jilted lover in the of "Nobody Knows the Trouble I've Seen" arena. Envy, not jealousy. When someone says they're 'jealous', they almost always mean...

    B Graphing trip efficiency - distance over time

    Here it is, simplified and spread over in 2 steps: Blue is the primary data, showing distance over time (speed) at any given time. Red (AC) is the total average speed (total distance / total time). Green (BC) is the average speed remaining (remaning distance over remaining time). The key here...

    B Graphing trip efficiency - distance over time

    The grey curve is derived from the grey numbers at the right. The grey numbers are simply the rainbow coloured-numbers, converted to a common denominator. The rainbow-coloured numbers are samples of the distance remaining per time remaining. The rainbow numbers are not instantaneous speed at...

    Like a doctor that can't care for a pregnant patient if they've never been through a pregnancy themselves? What makes you think an 11 year old can't have had their heart-broken? Childhood is filled with heart-break. Or do you mean that only romantic heart-breaks count?

    B Why 186,282?

    This whole thing is beginning to sound like a tautology. :sorry: It's turtles all the way down. Are any of these values taken from nature, as opposed to a self-referential (what did Ibix call it?) spiral of metrology?

    B Why 186,282?

    Sure. But ultimately, those other constants are constants of nature - they are observed - are they not? I mean, independent of our theories - they're more than just balancing numbers that make the equations work.
