The next time someone asks you where the biggest ocean is, point them toward Jupiter. While earth harbours about 320 million cubic miles(1,333 cubic km)of water, our planet is practically a desert compared to the rest of the Solar System.

    A moon of Jupiter called Europa, for example, which is roughly the size of our own Moon, likely hides a subsurface ocean with more than twice as much water as there is on Earth.

    Yet even that pales into insignificance in comparison to Europa's neighbour Ganymede; more than 30 times as much water as our home planet is thought to reside there as liquid and ice.

    And scientists keep finding more water wherever they look. On September 28, researchers reported that Dione — a small moon of Saturn — probably has a subsurface ocean, too.

    To see just how Earth stacks up against other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA's Jet Propulsion Laboratory who's calculated the numbers on just how much water might be out there.

    In order of how much water they have, from the least to the most, they are: Enceladus, Dione, Earth, Europa, Pluto, Triton, Callisto, Titan, and Ganymede. Mimas, a moon of Saturn, and Ceres, the largest asteroid in the Solar System, are also thought to have subsurface oceans —but scientists aren't yet sure how big each one might be.

    Personal computers and the Internet give people new choices about how to spend their time.

    Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.

    E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren't necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she'd been born before electronic mail became such a practical tool.

    The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun, see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.

    With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.

    E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.

    We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don't take the place of any of the old ways.

    At 23 I applied for full-time positions with no intention of working five days a week. As a housewife, I had two pre-school children then but wanted to work three days a week.

    This was a huge deal for me. I needed to work, but also wanted to spend time with my children while they were young. I didn't want to miss out on school drop-offs and pick-ups. But I also didn't want to miss out on the opportunity of promotion.

    Before the interviews, I prepared a plan of how I was going to make this work for me and the employer. I saw it as a two-way agreement — the business adapting to me and me adapting to the business.

    Finally I became a member of EY at 33. EY was the only firm that seemed receptive to my plan; in fact, we spent time during that first interview talking about how we could make it work together. Most importantly, the person interviewing me worked flexibly too — four days a week.

    I appreciated that I'm one of the lucky ones. Even 10 years on, flexible hiring and working remains the exception rather than the rule for most.

    What will help shift views and behavior, in addition to organizations updating their hiring policies, is talking more openly about how most of us organize our day around our responsibilities. We all have a life outside of work and we shouldn't be embarrassed to talk about it, even during a job interview.

    It's a change in the way of thinking, not just for employers but employees too. In the early days I was confident about my ability but I probably did have a preconception (先入之见) that working part-time would limit my career progression. What I quickly realized was that if I took responsibility for my development, I could make sure that I got the same opportunities as if I was working full-time. So I offered solutions to how we could make it work, and it made me stand out.
