Discover everything you need to know about biology, with the simplest most visual guide to the science of life. How do vaccines work? What is special about stem cells? How did we evolve from bacteria? The science of life can be dauntingly complex, and it can be hard to separate "good" science from "bad", fundamental truths from the much-hyped breakthroughs reported in the media. With clear, easy-to-understand graphics and packed with fascinating facts, How Biology Works demystifies both the core biology that may have eluded us at school, and the cutting-edge life science that makes the news, answering the questions that spark our curiosity. With power to every page, this striking science book: - Is illustrated entirely by specially commissioned, boldly-colored, distinctive, flat, vector graphics that explain each topic clearly and engagingly.
- Uses clear, distinctive, eye-catching graphics to make even complex biology easy to understand.
- Offers a practical, no-nonsense approach to each subject. Building from life's fundamental ingredients, such as carbon and water, the book explains chemical processes in living cells, controlled by the ultimate biochemical, DNA. It shows how DNA is made of units called genes, which are shuffled in each generation of offspring, leading to variation and evolution. It covers topics from school biology, such as how plants work and how animals, including humans, work, and goes on to ecology and biotechnology. Beyond school science, however, it covers the background to the latest medical technology and biotechnology: how gene therapy works, what stem-cell research is achieving, and how our immune systems, boosted by vaccines, are in an arms race with ever-mutating viruses and other pathogens. At DK, we believe in the power of discovery. So why stop there? How Biology Works is part of DK's widely successful How Stuff Works series. Discover the inner workings of the mind with How the Brain Works, succeed in all things science with How Science Works and discover the cosmos like you've never known before with How Space Works. Whatever topic sparks your interests, there's a plethora of knowledge to discover!

Authentic Docs for great price!
The boots I purchased were Chelsea 2976 in Nappa leather (not the brown Crazy Horse, but the Black; such nice and soft leather!) and unisex size men's 7/women's 8/EU 39 (I'm normally a women's US 9/EU 40, but that's what fit best--see notes on sizing below).
Considering the price, I was a little skeptical that these were genuinely Dr. Marten's, so I ended up bring them into a store to verify before wearing them--and multiple salespeople, who had worked for the company for 7+ years, said they looked like the real deal to them, which is amazing for the price (I got them when they were $99 online, but $160 in store; may have been a sale...?).
Before ordering, I also visited the store to get the right sizing--Dr. Marten's doesn't sell my normal size in the US (EU 40), so I needed help figuring out what to buy. In the end that was either a women's EU 41 or a unisex 39. Dr. Marten's women's sizes are cut more narrow, so if purchasing women's, I needed a longer shoe to give my toes more space (EU 41, which they say is a women's US 9 but on many shoes EU 41 is a US 9.5 or even US 10). Unisex sizes are wider, so I was fine with a shorter length (EU 39). In the end, the only real difference between the women's sizing and men's sizing on the Chelsea boot was at the ankle; for some reason, the women's 41 had more of a gap at the ankle and I worried that might make it rub/blister more, so I went with unisex sizing. It might also depend on the boot, so I'd say go to the store for sizing before purchasing online.
Once I got them & verified their authenticity, I got a but of things to help with weatherizing them and breaking them in (Dr. Marten's has a great kit! And, double thick socks). I did get a bad blister wearing them too long & uphill on the first day (and I had to get used to their weight; I don't have many heavier shoes). But, I used Compeed patches for the blister (should have put them on to prevent, but it was fine once they were on) and after a week of wearing them a little bit at a time, they are now super comfortable and I love them! Highly recommend!

Function and style
Size: 11 Women/10 Men, Color: Black Blizzard Wp
Ideal boot for the winter, snow, mud, etc. Protect your feet beautifully, stylishly.
Tip: Wear with two socks to help break in for the first couple weeks.
If you are a half size, round up.
This is the model without laces, makes for easy slip on / slip off for those pesky people who insist on having you take off your shoes at their house! Ha ha, you know who you are.

Size up for a little bit of heel slip
Size: 9 Women/8 Men, Color: Black Nappa
It’s still a doc and the air sole with bottom out kinda quick but it’s comfortable at first. Size up for a little bit of heel slip so you don’t get heel blisters but not too big of a size jump. Think of it kind of like a cowboy boot size

Comfy, don't require "breaking in"
Size: 8 Women/7 Men, Color: Dark Brown Valor Wp
Great fit, and both my pairs of Chelsea boots required way less breaking in than other Dr. Martens I own. Hold up to frequent use and I love the fleece lining for colder days.
