The Black Hole Becomes Visible With Half A Ton Of Hard Drives

Brace yourself. You can finally see how a black hole looks like. Up until today, no one really knew how a black hole looked like.

Finally, the day has come but it was no easy task.

The newly released image of a black hole (below) is a watershed moment for physics. Finally, we can put some of Einstein’s most famous predictions from a century ago to the test, but it was not as easy as pointing a big lens at the M87 galaxy and pressing a button. It took years of work and the collaboration of more than 200 scientists to make it happen. It also required about half a ton of hard drives.

What’s interesting about how the snapshot of the black hole was the length of time it took to put it together. It took years and a network of telescopes from around the world to capture the first real image of the black hole.

Data collection for the historic black hole image began in 2017 with a coordinated effort called the Event Horizon Telescope (EHT). That isn’t a single instrument but rather a collection of seven radio telescopes from around the world. The EHT used a principle called interferometry to combine the capacity of all those telescopes, creating a “virtual” telescope the size of the Earth.

The EHT had to collect a huge volume of data to deliver us this one image. Dan Marrone, Associate Professor of Astronomy at the University of Arizona says the EHT team had to install specialized super-fast data recorders on the various radio telescopes to handle the influx of measurements.

The now-famous image of a black hole comes from data collected over a period of seven days. At the end of that observation, the EHT didn’t have an image — it had a mountain of data.

The data collected was just too massive for the internet to handle. The hard drives had to be flown by plane.

According to Marrone, 5 petabytes is equal to 5,000 years of MP3 audio. There’s simply no way to send that much data efficiently over the internet. It’s faster to actually ship the hard drives to collaborators around the world. That’s why MIT has 1,000 pounds of hard drives sitting in its Haystack Observatory labs.

Thanks to the EHT project, black holes are no longer just illustrations on text books. They are real.

The historic black hole snapshot not only puts to test Einstein’s predictions. It also sheds a new light on the general relativity of black holes.

Another interesting thing about the historic snapshot of the …

Getting Clients to Work Your Way

They say that “the customer is always right”. And while that may be true (most of the time), it certainly doesn’t mean that we have to bend over backwards for them in every instance. I should know, as I spent years attempting to contort myself to fit whatever clients wanted.

One area that is particularly tough to manage is when it comes to our process for getting things done. If you deal with multiple clients, each one of them has their own distinct way of working. Some are night owls and feel the need to send email when the moon is out. Others expect a lot of in-person meetings – something difficult for a busy web designer to fit into their schedule.

Trying to accommodate each and every client’s way of working often leads to chaos. It makes getting things done more difficult and will leave you scrambling to find some level of consistency in your workflow.

Sound terrible? Sound familiar? If you’re banging your head against the wall, know that change is possible! Let’s take a look at some ideas for getting clients to work in a way that benefits you.

Create Processes That Work for You

During the early part of my career as a freelancer, I really had no process for getting things done. That is, unless you count waking up and walking over to the home office. There wasn’t any real organization to speak of and I haphazardly went back-and-forth between tasks. Sort of like a single-player game of table tennis.

Not only that, I was often running out to meetings and taking a seemingly endless number of phone calls. This led to a lot of stress, and a pile of work that I couldn’t seem to get through. Eventually, I realized that a change was needed.

So, I started putting some processes in place. Each one acts as a bit of a boundary for both my clients and myself. They’re not perfect, but have produced some positive results. Among them:

Limit Meetings

I now avoid going out to meetings when possible, and they are usually reserved for higher-revenue clients. As most of my clients are based at least a half hour from my office, I found that, when accounting for travel, even a short meeting tended to take up several hours of work time. Replacing meetings with phone calls or video chats (which I limit to specific hours) has saved a ton of time, while keeping the lines of communication open.

Reserve Time for Each Task

Understandably, clients tend to want things done “as soon as possible”. At the same time, it’s not always …

How to Insert a GIF Into PowerPoint

GIFs are more popular than ever right now and they can be a great way to add a touch of personality, character, or humor to your PowerPoint presentation. We’re going to quickly cover how to insert a GIF into PowerPoint in a few quick, easy steps!

Of course, you have to find the right image to use in a presentation. If you’re going for humor, aim for something short, punchy, and easy to read from a distance as well! If you’re using a GIF to explain a workflow in your app or product, try zooming in on the areas you’re getting people to look at.

Once you have your GIF sorted, here are the steps you need to focus on in order to insert your GIF into PowerPoint.

Choose the Slide to Add the GIF To

First up, choose the slide you’d like to add your GIF to. Make some space for it to fit in with your design, and think about the type of background and style you’ll use to ensure that it stands out.

You should consider the option of a full-screen GIF as well, creating a slide dedicated to it. Nothing creates a big, bold impact like a full-screen GIF!

Download Your GIF + Open File Picker

It’s best to download your GIF to your computer (by right-clicking the image and selecting “Save Image As…”). This means you’re not relying on the computer you present on having an internet connection, which is never a guarantee!

Browse the menu in PowerPoint to find the “Insert” tab. Choose “Pictures”, and then PowerPoint will ask you to choose the GIF that you’ve just downloaded.

Choose Your GIF

Now you will need to navigate to the location of your animated GIF and then click Insert or Open. This will drop it into the current slide. You can make some minor enhancements to the GIF if you’d like (things like adding a frame or border to make it stand out). Or, you can resize it to cover the full slide if that’s the look you’re going for.

How to Play the Animation

You can test out the animation by choosing “Slide Show” from the menu, then “From Current Slide”. This will show you a preview of how your presentation will look when you reach the slide that contains your GIF.

You should find that the animation plays automatically when you get to the slide. Simple!

Thankfully, adding and playing a GIF file in PowerPoint is really quite simple, and can work splendidly as a way to add some life and interest to your slide deck.

That said, deploy tactically… No-one wants a …

Data Visualization in Web Design: 12 Stunning Examples

Data, data, everywhere. But what do you do with it? Today, we’ve collected 12 stunning examples of data visualizations in website design to jump-start your thinking about how to work with data.

We live in a time where the ability to showcase data in new and interesting ways can be a huge asset as a designer.

Whether you have a massive collection of numbers or just information that you want to showcase, this design style can be a great tool in your kit.

1. History of the NFL

data visualization

With decades of data spanning 32 teams, there’s plenty of information available about games in the NFL. FiveThirtyEight boiled it all down into a series of interactive graphs that you can view by team to see the ebbs and flows of football history.

The best thing about this data visualization is that it is super simple. The lines show wins and losses. But with clicks and hovers, the data springs to life: You can get scores, dates, and records for every single game overlaid on a map of the averages for the entire league. (So you can see if your team is ahead of or behind the pack.)

2. Selfiecity

data visualization

Selfies are more than just a fun set of photos. Selfiecity uses rich media visualizations to assemble thousands of photos to find demographic information about the people who take them.

What’s cool about this data set is that while it is all visual – thousands of photos – you can start to see patterns, such as the style of selfie people take in different places, whether women or men take more photos and the ages of selfie-takers. While there are some statistics and numbers here, this data is plotted using photos in a giant grid.

3. Largest Vocabulary in Hip Hop

data visualization

This project from ThePudding shows that data doesn’t always have to be numbered. It analyzes the number of unique words used in hip hop lyrics and plots the biggest vocabularies by the number of words with images of the artist.

Here’s how it works: “It compares the number of unique words used by some of the most famous artists in hip hop (that is, an example of a quantitive view of lyricism, once proposed by Tahir Hemphill). I used each artist’s first 35,000 lyrics. This way, prolific artists, such as Jay-Z, can be compared to newer artists, such as Drake.”

The simple black and white design of the plotted chart is visually interesting and makes it easy to see which artists are ahead of the pack. (Or you can use the more interactive tools and search for specific artists.) You can …
