Perseverance

Perseverance

Thursday 18, 2021 was the date that the perseverance rover from NASA overcame the “7 minutes of terror” to land on the Mars surface. This made it the fifth rover to ever reach make it to the red planet.

Perseverance: “continued effort to do or achieve something despite difficulties, failure, or opposition : the action or condition or an instance of persevering : steadfastness.”

Like its name, perseverance was built through determination and hard work. The team had been working on the project for over 10 years, and it all boiled down to the “seven minutes of terror” when the crew frantically scrambled to get everything right so as to not reach a sudden and disappointing end to their voyage.

There are many reasons to justify missions to Mars, among those being the hyped possibility of life, relative ease to travel between planets (there are alignment opportunities around every two years), and scientific curiosity of the possibilities of the planet so close to ours.

The nail-biting sequence if pretty stressful to watch, even for those not following the story. Some of the thrill and nervousness of the crew and team was shared by the millions of viewers throughout the world eagerly watched the landing, having marked their calendars for weeks.

The rover has sent out pictures of the Martian surface back to Earth, the group quickly posting them online and operating its own twitter account! The first pictures were black and white, but the newer ones sent Friday were in full color, showing off the famous red surface of the planet.

The rover will operate in icy temperatures. Mars has an average surface temperature of negative eighty degrees Fahrenheit, or negative sixty degrees Celsius!

Congratulations to the NASA team and the scientific community, both national and international for this monumental and historic achievement. Perseverance has joined the ranks of Sojourner, Opportunity, Spirit, and Curiosity, the previous four rovers to ever successfully make the journey. The team has proved to us the cliché “anything is possible with perseverance and determination”

Titanium Dioxide- Miracle Paint?

Titanium dioxide, TiO2, is the basis for a huge variety and number of different products that many of us use daily. Used for over a century. It is used in paints for its high whiteness and opacity, and its ability to mask or hide.

Titanium dioxide is also used in other products. Ranging from chocolates for smoothness and color (in relatively small doses) to sunscreen and lotions for its color, along with a DIY market of over 3 billion dollars.

The only problem with this white powder is its potential carcinogenic properties. The FDA has ruled that there is no harm in uses of under 1% in foods, and manufacturers are rarely required to list it as an ingredient. Unfortunately, The International Agency for Research on Cancer (IARC) has classified titanium dioxide as “possibly carcinogenic to humans,” due to increased lung tumors in animals linked to consumption.

For now, there’s little to do about it, and you’re unlikely to be able to avoid it in your food or paint, and the world is dangerous enough that titanium dioxide doesn’t have to be in our list of worries anyway.

Cauliflower

Cauliflower

Have you ever looked at cauliflower? Really looked at it? The thing that “looks like broccoli, but white”? The “miniature tree” ?

It’s a fascinating thing.

You might not think it, but it really is amazing.

Take off a piece off the top or side,

and you’ll see that it looks

just like the piece it came from.

Take a piece off of that.

Again, it looks identical.

Same proportions, just miniaturized.

Almost like a snow globe,

a view into another world,

in a smaller form.

Beauty in structure,

in shape and form.

Together to make

something better

Artificial Intelligence

Artificial Intelligence

Artificial Intelligence- By Purusha Shirvani

We often think about ourselves as living in a “modern world,” imagining the twenty-first century as the height of human civilization to date, with advances in all forms of technology, ranging from healthcare, medicine, prevention, and detection to every area like recreation, forensics, transportation, and in almost every other aspect of our lives.


This was all accomplished by what we like to proudly call our “superior intellect” to the other inhabitants of this planet. What some have begun worrying about throughout the last century, however, is that one day we might NOT be the most intelligent species on Earth. This would make us unable to rule this land the way we have been doing for millennia. This perceived threat is usually associated with fears that our creations might be the ones accelerating our way to this demise. This would make our improvement and advances being a double-edged blade.


Double Edged Blade

———————-


This double-edged blade can take many forms, but one of the most famous examples is Artificial Intelligence. An often misused label for functions that would otherwise require human intelligence is also confused with machine learning. Machine learning is a subset of artificial intelligence that involves learning and improving by itself. Ever since the introduction of ENIAC (one of the first computers, it stood for Electronic Numerical Integrator and Computer ), fears of the machines one day overtaking us grew and were often expressed in the form of stories, novels, and sometimes conspiracy theories

However, unlike what some of us think, the fear is not wholly baseless, nor is it “far off on the horizon.” Stephen Hawking once said that artificial intelligence could be the “worst event in the history of our civilization.” He also urged creators to “employ best practice and effective management.” Turing has proven that it’s logically impossible to know if every program reaches a conclusion and halts; or if it will loop forever trying to find a solution.*

That means that simple rules such as “minimize human suffering” or “never harm humans” could have unknown consequences or direct the AI in a way we could never have predicted. This restriction would, in effect, make containment algorithms that seek to do precisely that unusable. A super-intelligent AI with unknown or greater than human capacity would thus be unpredictable and uncontrollable by extension.

Kind of scary, but it’s still a long ways off, right?

Young Man

Young Man

Young Man- By Purusha Shirvani

—————————————————————

He walks into the room.

Disheveled hair, curly, black and brilliant,

Glasses sliding down his nose,

Reaching down,

to push them up again

Walking-

hesitant, towards

The center, between the chairs

Pausing and looking around discretely,

Trying to hold his head high,

Back straight, feet parallel, just

Like his father had told him

Heart beating

A thousand times a second

Towards the light,

Sure of his fate

Virtual Humanity

Virtual Humanity- By Purusha Shirvani

——————————————————————————————————————–

March is the month of COVID 19. Around March, schools across the United States and in dozens of other countries were officially and abruptly closed. March 11, 2020, was the day that the WHO finally classified COVID-19 as a pandemic.

With the sudden and unexpected start of a worldwide pandemic, the international community was thrown into disarray and uncertainty. We weren’t ready. Abruptly thrown into a virtual world, we needed to adapt and change our beliefs. We often talk about how things will go “back to normal,” but nearly a year after the start of the pandemic, the world has changed it’s norm forever. Never before have most students (and some teachers!) attended school in their pajamas, or the workplace been one click away. “Hanging out with friends to grab a bite” has changed to “zoom parties” and “have your own food!”

No longer are the majority of our interactions face-to-face. Never before have work meetings and school presentations been interrupted by younger siblings, children, and pets. Massive buildings put out for rent because there’s not a single soul in them. Workplaces with empty parking lots and hospitals with lines stretching to the next city. Children unable to tell apart our expressions because our masks cover them. These are aspects of culture, and by extension, humanity.

Albert Einstein once said, “It has become appallingly obvious that our technology has exceeded our humanity,” and he was right. Classes, concerts, meetings, parties, reunions, and even exercises are now available by simply clicking on a link. None of these could previously be accepted into our culture. The change in our routines and personal lives can actually be a blessing in disguise. We can use this as an opportunity to redefine and shape our humanity to match the technology we have today. This will bridge the gap between what we are right now and a virtual humanity.

The interesting thing is that the whole world is experiencing the same things and moving in the same direction. Maya Angelou once said, “It’s good to remember that in crises, natural crises, human beings forget for awhile their ignorances, their biases, their prejudices. For a little while, neighbors help neighbors and strangers help strangers”. When the National Health Service in Britain sent out a call for help regarding COVID 19, it took less than 24 hours for half a million people in the country to volunteer.

This is the first time the entire world has faced the same problems, regardless of race, gender, or background. Although tragic, it is a tragedy that unites us. Our nation came together in a moment that could have broken us. We face a common enemy through our challenges and difficulties, one that we all want to vanquish. This is why scientists are combining a Russian and British vaccine to produce results better than any one of them could alone. This is why the World Health Organization, along with dozens of developed countries, is directing COVAX, a program aimed at fair and equitable vaccine distribution to countries that need it most, despite lack of resources or funds. It is an incredibly rare opportunity to see over 173 countries unite to produce something that benefits everyone. 

We have gained some very costly experience over the past year, but this marks our rapid and forced transition to a new age of humanity; an age of virtual humanity. It’s a “sink or swim” situation, and humanity as a whole has always been tenacious.

Industrial Revolution

Industrial Revolution

The Industrial Revolution: A period of great change throughout the world, and one which- unlike some others, can never be reverted, altering the course of history forever. With this change came developments, good, and bad.

Why The History Lesson?

While interesting for some, a lot of people aren’t looking for a trip down memory lane back behind a cramped desk in class.

The importance of the Industrial Revolution lies in its effects today. The continued and increased rise of slavery across the Western World, the unprecedented and exponential rate of development of technology leading to the following second, third, and eventual fourth Industrial Revolution in quick succession compared to the centuries- if not millennia of little development.

All of these changes set the stage for the current atmosphere and many aspects in the daily lives of people in “the first world”. Racial dynamics, technology, culture, and behaviors are all at least partly attributed to one of the biggest and most important changes in history.
