Big data:Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered (known as the "three v's" of big data).

Big data is a great quantity of diverse information that arrives in increasing volumes and with ever-higher velocity.
Big data can be structured (often numeric, easily formatted and stored) or unstructured (more free-form, less quantifiable).
Nearly every department in a company can utilize findings from big data analysis, but handling its clutter and noise can pose problems.
Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins.
Big data is most often stored in computer databases and is analyzed using software specifically designed to handle large, complex data sets.
How Big Data Works
Big data can be categorized as unstructured or structured. Structured data consists of information already managed by the organization in databases and spreadsheets; it is frequently numeric in nature. Unstructured data is information that is unorganized and does not fall into a predetermined model or format. It includes data gathered from social media sources, which help institutions gather information on customer needs.






 






Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins. The presence of sensors and other inputs in smart devices allows for data to be gathered across a broad spectrum of situations and circumstances.

At the most basic level, nutrition is about eating a regular, balanced diet. Good nutrition helps fuel your body. The foods you eat supply the nutrients your body needs to maintain your brain, muscle, bone, nerves, skin, blood circulation, and immune system. Proper nutrition also helps protect you from illness and disease such as heart disease, diabetes, cancer, and osteoporosis.
There are two major classes of nutrients in food: macronutrients and micronutrients. Macronutrients are carbohydrates, protein, and fat. They supply energy (in the form of calories) and serve as the building blocks for muscles and tissues.
In comparison, micronutrients are individual vitamins and minerals. They are divided into four categories: water-soluble vitamins, fat-soluble vitamins, microminerals, and trace minerals.
 
While most foods in plant-based diets offer important health benefits, certain ones stand out. These "superfoods" pack the biggest nutritional punch. People should try to eat some of these healthy foods every day or as often as possible. They include the following:

Berries. High in fiber, berries are naturally sweet, and their rich colors mean they are high in antioxidants and disease-fighting nutrients.
Fatty fish. Fatty fish can be a good source of protein and omega-3 fatty acids, which help prevent heart disease. Those with the highest omega-3 content are salmon, mackerel, trout, anchovies, and sardines.
Leafy greens. Dark, leafy greens are a good source of vitamin A, vitamin C, and calcium, as well as several phytochemicals (chemicals made by plants) that fight inflammation and protect cells from damage.
Nuts. Hazelnuts, walnuts, almonds, and pecans are good plant protein sources. They also contain monounsaturated fats, which may be a factor in reducing the risk of heart disease.
Olive oil. Olive oil is a good source of vitamin E, polyphenols, and monounsaturated fatty acids, all of which help reduce the risk of heart disease.
Whole grains. A good source of soluble and insoluble fiber, whole grains also contain several B vitamins and minerals. They have been shown to lower cholesterol and protect against heart disease and diabetes.
Yogurt. A good source of calcium and protein, yogurt contains live cultures called probiotics. These "good bacteria" can protect the body from other harmful bacteria.
Cruciferous vegetables. These include broccoli, Brussels sprouts, cabbage, cauliflower, collard greens, kale, kohlrabi, mustard greens, radishes, and turnips. They are an excellent source of fiber, vitamins, and phytochemicals, which may help prevent some types of cancer.
Legumes. This broad category includes kidney, black, red, and garbanzo beans, soybeans, and peas. Legumes are an excellent source of fiber, folate, and protein; studies show they can help reduce the risk of heart disease.

 

The classic egg drop experiment gets reinvented as a driving question for physics students to explore a real-world problem.

By Suzie Boss
July 26, 2018
When a teenager climbs atop his desk and drops an object to the floor, teacher Johnny Devine doesn’t object. Far from it—he’s as eager as the rest of the class to see what happens next.

In a split second, the student and his teammates get positive feedback for the object they have cobbled together by hand. A small parachute made of plastic and held in place with duct tape opens as planned, slowing the descent and easing the cargo to a safe landing. Students exchange quick smiles of satisfaction as they record data. Their mission isn’t accomplished yet, but today’s test run brings them one step closer to success as aspiring aerospace engineers.



To boost engagement in challenging science content, Devine has his students tackle the same problems that professional scientists and engineers wrestle with. “Right away, they know that what they are learning can be applied to an actual career,” Devine says. “Students are motivated because it’s a real task.”

From the start of Mission to Mars, students know that expert engineers from local aerospace companies will evaluate their final working models of Mars landing devices. Their models will have to reflect the students’ best thinking about how to get a payload from orbit onto the surface of the Red Planet without damaging the goods inside. While real Mars landings involve multimillion-dollar equipment, students’ launchers will carry four fragile eggs.

THE ROAD MAP

Although the project gives students considerable freedom, it unfolds through a series of carefully designed stages, each focused on specific learning goals. Having a detailed project plan “creates a roadmap,” Devine explains, “for the students to really track their progress and see how what they’re learning connects back to the guiding question: How can we successfully land a rover on Mars?”

Before introducing technical content, Devine wants students to visualize what space scientists actually do. By watching videos of engineers who design entry, descent, and landing systems for spacecraft, students start getting into character for the work ahead.

Devine introduces a series of hands-on activities as the project unfolds to help students put physics concepts into action. They learn about air resistance, for instance, by experimenting with parachute designs and wrestling with a real challenge: How will they slow their landers to a reasonable speed for entry into the thin Martian atmosphere?

To apply the concept of change in momentum, students design airbag systems to go on the bottom of their landers—a location aptly called the crumple zone. They experiment with bubble wrap and other materials as potential cushioners for their cargo.

As the grand finale approaches, students keep using what they learn to test, analyze, and modify their designs. “You have to repeat the equations with different trials,” one student explains. “Being able to use that math over and over again helps it stick.”

Much of the hands-on learning in this PBL classroom “might look like a traditional physics lab,” Devine acknowledges, with students learning concepts through inquiry investigations. What’s different is the teacher’s ongoing reminder “to make sure students stay in character” as systems engineers. Each lab investigation relates back to their driving question and creates more opportunities for Devine to ask probing questions and formatively assess his students’ understanding. “We do a lot of framing in and framing out after each of those lessons so students have the chance to reflect and connect it back,” the teacher explains.

EXPERT CONVERSATIONS

When it is finally time for students to launch their precious cargo off a second-story landing, engineers from local aerospace companies are standing by to assess results. How many eggs in each lander will survive the fall?

Even more important than the test data are the discussions between experts and students. One engineer, for instance, asks to see earlier versions of a team’s design and hear about the tests that led to modifications. A student named Elizabeth perks up when she hears engineers using the same technical vocabulary that she and her classmates have learned. “It was kind of a connection—this is actually a thing that goes on,” she says.

“They had really deep, meaningful conversations so that students could practice communicating their justification for their designs,” Devine says. Hearing them use academic language and apply physics concepts tells the teacher that students deeply understand the science behind their designs. “At the end of the day, that’s what I’m most concerned about,” he says.

Does this test have other names?
ESR, sed rate
What is this test?
Erythrocyte sedimentation rate (ESR) is a blood test. It measures how quickly erythrocytes, or red blood cells, separate from a blood sample that has been treated so the blood will not clot. During this test, a small amount of your blood will be put in an upright tube. A lab specialist will measure the rate that your red blood cells settle toward the bottom of the tube after 1 hour.
If you have a condition that causes inflammation or cell damage, your red blood cells tend to clump together. This makes them heavier, so they settle faster. The faster your red blood cells settle and fall, the higher your ESR. A high ESR tells your healthcare provider that you may have an active disease process in your body.
Why do I need this test?
You may need this test if you have symptoms of one of the diseases that may cause ESR to go up.
You may also need this test if you have already been diagnosed with a disease that causes a high ESR. The test can allow your healthcare provider to see how well you are responding to treatment.
The ESR blood test is most useful for diagnosing or monitoring diseases that cause pain and swelling from inflammation. Other symptoms may include fever and weight loss. These diseases include:


Temporal arteritis


Rheumatoid arthritis


Polymyalgia rheumatica


ESR is not used as a screening test in people who do not have symptoms or to diagnose disease because many conditions can cause it to increase. It might also go up in many normal cases. ESR doesn't tell your healthcare provider whether you have a specific disease. It only suggests that you may have an active disease process in your body.
What other tests might I have along with this test?
You may have other tests if your healthcare provider is doing this test to diagnose a disease. One of these tests is called a C-reactive protein test, or CRP. This test also measures active inflammation in the body.
Your healthcare provider may do an ESR alone if they are monitoring a disease you already have.
Because ESR tells your healthcare provider only what is happening right now, you may need to have the test repeated over time.
What do my test results mean?
Test results may vary depending on your age, gender, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your healthcare provider what your test results mean for you.
ESR is measured in millimeters per hour (mm/hr). The normal values are:


0 to 15 mm/hr in men


0 to 20 mm/hr in women


ESR above 100 mm/h is most likely caused by an active disease. For instance, you may have:


A disease that causes inflammation in your body


An active infection


Cancer


Heart disease


Kidney disease


Blood disease


Diabetes


Collagen vascular disease


How is this test done?
The test is done with a blood sample. A needle is used to draw blood from a vein in your arm or hand.
Does this test pose any risks?
Having a blood test with a needle carries some risks. These include bleeding, infection, bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may feel a slight sting or pain. Afterward, the site may be sore.
What might affect my test results?
Many things that are not active diseases can increase your ESR. These include:


Pregnancy


Old age


Being female


Having a menstrual period


Having recently eaten a fatty meal


Being obese


Taking certain medicines


How do I get ready for this test?
You don't need to prepare for this test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illegal drugs you may use. Tell your healthcare provider if you ate a fatty meal recently, if you are having your period, or if you may be pregnant.
