Raffles & Giveaways

[center][i][center][size=7]Dragons for Science![/size][/center][/i] You step into a large, brightly lit white room. As the metal door swings shut behind you and your eyes adjust to the light, you find yourself quite suddenly faced by a large Skydancer in a white lab coat. The electricity that seems to be emanating from him makes your hide prickle. [url=https://flightrising.com/main.php?dragon=42219850] [img]https://flightrising.com/rendern/350/422199/42219850_350.png[/img] [/url] "[i]Greetings, greetings![/i]" he thunders. "[i]I suppose you're here for a new lab- er, I mean, lair member! Yes![/i]" He waves at a banner hanging on the wall behind him: [i][center][size=7]Free Dragons to Enquiring Minds[/size][/center][/i] Various implements, flasks and machinery can be seen scattered on the lab benches surrounding the room. At set intervals, large portraits featuring a dragon can be seen hanging behind these benches. "[i]All of these lovely dragons here are in search of a new den to join... But![/i]" He shakes his wings, sending shivers of static up his feather tips and gestures at the benches, "[i]They all wish to be part of only the most intellectual of lairs. As such, if you can answer the questions they have set up, only then will they join you![/i]" He hands you a lab coat, cackling, "[i]Here you go! Please, let me know what you find!"[/i] [/center]

[size=7][u]How to play! [/u][/size] Dragons will be listed here besides some form of maths/ science question. If you can answer the question, I'll send you the dragon! Fill out the 'form' below! (Delete the example text and replace with your own). [columns]A large number of these questions are real-life examples of things I have to think about/ calculate in my day-to-day life in the lab as a researcher (though I have chucked in some basic science Q's). Doing this serves a dual purpose of reminding myself how to do these things, and serving as a bit of a looking-glass into what might go on in a research lab![nextcol][emoji=tundra star size=2][/columns] [size=7][b]Rules:[/b][/size] [LIST] [*]I am subscribed, no need to ping me! [*]You may only receive one dragon from this thread per week. [*]If the dragon is Unnamed, you must provide a name for it. [*]Answers to mathematical questions must show all relevant workings (these can be typed or a picture of hand-written words. Try to be legible though!) (I like [url=https://postimages.org/]PostImg[/url] as my image hosting site, but any works!) [*]Answers to theoretical questions must include at least one or two sentences containing your reasoning. [*]To prove you've read these, please include at least one dragon emoji with star-eyes in your post. [*]These dragons are preferably for those who wish to keep them. While the dragon you are given is yours to do with what you wish, those who participate just to get exalt or auction-house fodder will not be allowed to participate again. [*]If two people attempt a question for the same dragon, the most correct answer or the answer with the best working will 'win'. If both answers are excellent, the one posted first will win. (This is to firstly discourage rushed answers). [*]I run this in my free time - please bear with me if updates and replies are slow!

This is an awesome idea! Sadly, all math questions sound like this to me:

If Jane is driving 50 km/hr NE and Bob has three oranges, how long will it take for Jane to overcome the force of gravity so Bob's grandkids can have the correct alleles so they can pass on their green eyes?

Anyway, I hope you do really well and a free bump for you!

(ETA: I probably/eventually could do the work on the questions you asked. Your dragons ARE lovely. I just cannot get that frustrated right now!)

as a struggling bio uni student, i'm most impressed with your ability to superscript for significant figures but cannot (for the life of me) fathom any of the questions right now :')) maybe i'll try them out in the morning ^^;;; but free bump!!
