The Conversation U.S. launched its new book club with a bang – talking to mathematician Manil Suri about his nonfiction work “The Big Bang of Numbers: How to Build the Universe Using Only Math.” Suri, a previous author in The Conversation, has also written an award-winning fiction trilogy, in addition to being a professor of mathematics and statistics at the University of Maryland, Baltimore County.

Below is an edited excerpt from the book club discussion. You’re welcome to keep the conversation flowing by adding your own questions for Suri to the comments.

Watch the full book club meeting and leave your own question in the comments at the bottom of this article.

What is the Big Bang of numbers and where do you go from there in the book?

I think the story for me started way back when I was an undergraduate in Bombay. My algebra professor told us this very famous saying by Leopold Kronecker, the famous mathematician, that God gave us the integers and all the rest is the work of human beings. What he meant was that once you have the whole numbers – 1, 2, 3, 4 – which are somehow coming from heaven, then you can build up the rest of mathematics from it.

And then he went on and said, Hey, I can actually do better. I don’t need God. I can actually, as a mathematician, create the numbers out of nothing. And he showed us this marvelous, almost magic trick, where you start with something called the empty set and then you start building the numbers.

It was the closest I’ve been to a religious experience, almost like the walls just dissolved and suddenly there were numbers everywhere.

Once I started writing my novels, I was meeting a lot of people who were artists and writers. And they would always say, you know, we used to love math when we were in school, but afterward we never had a chance to really pursue it. And can you tell us something about your mathematics?

So, I started building a kind of talk, which started with this big bang, as I call it, building the numbers out of nothing. I finally decided I should write a math book, and it would be aimed at a wide audience.

And I said, well, can you go further? You can create the numbers, but can you actually start building everything, including the whole universe from that? So that was a way to try to lay out mathematics almost as a story where one thing follows from the other and everything is embedded in one narrative.

Who were you imagining to be your readers as you were writing the book?

There’s just so much joy to be had out of mathematics, so many things that you don’t really see in normal courses where the emphasis is always on doing the calculations, finding the right answer. So this book is written for people who want to really engage with mathematics on the level of ideas rather than get into computations and calculations.

After you set off your Big Bang of numbers, you dig in to some of life’s big questions. What do you see as math’s role in grappling with those big thoughts, like where the universe came from, why we even exist and so on?

Once you start talking about the Big Bang, what comes into your mind is creation. There is a doctrine called creatio ex nihilo, which is basically creating everything out of nothing.

That’s a cornerstone of many religions where God creates the universe out of nothing. It’s also in some sense being explored by physicists, where you have some sort of singularity and from that, everything emerges in the Big Bang.

So my thought was, both these areas, religion and physics, are in the public’s imagination much more than mathematics is. Is there a way to posit math as the creative force of everything?

Physicist Eugene Wigner, who was a Nobel laureate, talked about the “unreasonable effectiveness” of mathematics at describing everything in our physical universe. It’s so good at modeling physics and what have you. Could it be that math is really the true driving force of the universe? Rather than us just inventing it and using it to describe the universe, could the universe really be describing mathematics? Then the universe is just a physical manifestation, an approximation, if you will, of those mathematical ideas. It’s a completely different view of math.

There’s an ongoing debate over whether math is something that people invented or whether it’s something that exists independently of us. In the book, you say that perhaps the deepest insight that math can offer us is that it’s both of those things.

So the glib answer to your question whether math’s invented or discovered is that you have to create a new word. Instead of discovered or invented it’s “disvented.”

What I mean by that is simply that there are some questions we really can’t get to any kind of logical or supportable answer. One is the question of our own existence – people might believe one thing or the other, but it always comes down to: Is there some real purpose to our lives, or is our creation just something that happened randomly – you know, molecules getting together?

Now if we invent mathematics, then we’re inventing it for a purpose. If it just generates by itself, starting with emptiness, building around numbers in some strange realm that we don’t know about, then it’s just wafting around, purposeless.

Math has that duality that can’t be resolved. So it’s a metaphor, telling us, hey, you can’t decide for math, and you’ll never be able to decide for yourself about your own existence.

Can you tell us a bit about your previous books, the Indian novels?

The first one was called “The Death of Vishnu.” I went back to visit my parents in Mumbai in around 1995, and this man Vishnu, who used to live in our building and do errands, was dying on our steps. I started writing this as a short story.

It started going into a more philosophical realm when a writing teacher said, you know, Vishnu is also the name of the caretaker of the universe in Hindu mythology. So if you name somebody Vishnu, you need to somehow explore that. So that’s what opened up this whole new world for me.

The second book was “The Age of Shiva.” That one’s the journey of a woman right after India’s independence in 1947. She’s making her way in a very male-dominated world, and she’s not perfect.

Then the third one, I decided, OK, I need to put in some science and math characters. So “The City of Devi” actually has both a physicist and a statistician. Again it’s in Mumbai, set in the future with the threat of a nuclear war with Pakistan and a love triangle unfolding in front of that.

It’s kind of interesting. I thought that I was done with this mythical “where do we come from?” kind of philosophy that I had in the three books, but apparently not, because now “The Big Bang of Numbers” looks at it from a mathematical perspective.

Shakira’s net worth

After 12 albums, a tax evasion case, and now a towering bronze idol sculpted in her image, how much is Shakira worth more than 4 decades into her care…

Shakira’s considerable net worth is no surprise, given her massive popularity in Latin America, the U.S., and elsewhere. 

In fact, the belly-dancing contralto queen is the second-wealthiest Latin-America-born pop singer of all time after Gloria Estefan. (Interestingly, Estefan actually helped a young Shakira translate her breakout album “Laundry Service” into English, hugely propelling her stateside success.)

Since releasing her first record at age 13, Shakira has spent decades recording albums in both Spanish and English and performing all over the world. Over the course of her 40+ year career, she helped thrust Latin pop music into the American mainstream, paving the way for the subsequent success of massively popular modern acts like Karol G and Bad Bunny.

In late 2023, a 21-foot-tall bronze sculpture of Shakira, the barefoot belly dancer of Barranquilla, was unveiled at the city's waterfront. The statue was commissioned by the city's former mayor and other leadership.

In December 2023, a 21-foot-tall beachside bronze statue of the “Hips Don’t Lie” singer was unveiled in her Colombian hometown of Barranquilla, making her a permanent fixture in the city’s skyline and cementing her legacy as one of Latin America’s most influential entertainers.

After 12 albums, a plethora of film and television appearances, a highly publicized tax evasion case, and now a towering bronze idol sculpted in her image, how much is Shakira worth? What does her income look like? And how does she spend her money?

How much is Shakira worth?

In late 2023, Spanish sports and lifestyle publication Marca reported Shakira’s net worth at $400 million, citing Forbes as the figure’s source (although Forbes’ profile page for Shakira does not list a net worth — and didn’t when that article was published).

Most other sources list the singer’s wealth at an estimated $300 million, and almost all of these point to Celebrity Net Worth — a popular but dubious celebrity wealth estimation site — as the source for the figure.

A $300 million net worth would make Shakira the third-richest Latina pop star after Gloria Estefan ($500 million) and Jennifer Lopez ($400 million), and the second-richest Latin-America-born pop singer after Estefan (JLo is Puerto Rican but was born in New York).

Shakira’s income: How much does she make annually?

Entertainers like Shakira don’t have predictable paychecks like ordinary salaried professionals. Instead, annual take-home earnings vary quite a bit depending on each year’s album sales, royalties, film and television appearances, streaming revenue, and other sources of income. As one might expect, Shakira’s earnings have fluctuated quite a bit over the years.

From June 2018 to June 2019, for instance, Shakira was the 10th highest-earning female musician, grossing $35 million, according to Forbes. This wasn’t her first time gracing the top 10, though — back in 2012, she also landed the #10 spot, bringing in $20 million, according to Billboard.

In 2023, Billboard listed Shakira as the 16th-highest-grossing Latin artist of all time.

How much does Shakira make from her concerts and tours?

A large part of Shakira’s wealth comes from her world tours, during which she sometimes sells out massive stadiums and arenas full of passionate fans eager to see her dance and sing live.

According to a 2020 report by Pollstar, she sold over 2.7 million tickets across 190 shows that grossed over $189 million between 2000 and 2020. This landed her the 19th spot on a list of female musicians ranked by touring revenue during that period. In 2023, Billboard reported a more modest touring revenue figure of $108.1 million across 120 shows.

In 2003, Shakira reportedly generated over $4 million from a single show on Valentine’s Day at Foro Sol in Mexico City. 15 years later, in 2018, Shakira grossed around $76.5 million from her El Dorado World Tour, according to Touring Data.

How much has Shakira made from her album sales?

According to a 2023 profile in Variety, Shakira has sold over 100 million records throughout her career. “Laundry Service,” the pop icon’s fifth studio album, was her most successful, selling over 13 million copies worldwide, according to TheRichest.

Exactly how much money Shakira has taken home from her album sales is unclear, but in 2008, it was widely reported that she signed a 10-year contract with LiveNation to the tune of between $70 and $100 million to release her subsequent albums and manage her tours.

How much did Shakira make from her Super Bowl and World Cup performances?

Shakira co-wrote one of her biggest hits, “Waka Waka (This Time for Africa),” after FIFA selected her to create the official anthem for the 2010 World Cup in South Africa. She performed the song, along with several of her existing fan-favorite tracks, during the event’s opening ceremonies. TheThings reported in 2023 that the song generated $1.4 million in revenue, citing Popnable for the figure.

A decade later, 2020’s Superbowl halftime show featured Shakira and Jennifer Lopez as co-headliners with guest performances by Bad Bunny and J Balvin. The 14-minute performance was widely praised as a high-energy celebration of Latin music and dance, but as is typical for Super Bowl shows, neither Shakira nor JLo was compensated beyond expenses and production costs.

The exposure value that comes with performing in the Super Bowl Halftime Show, though, is significant. It is typically the most-watched television event in the U.S. each year, and in 2020, a 30-second Super Bowl ad spot cost between $5 and $6 million.

How much did Shakira make as a coach on “The Voice?”

Shakira served as a team coach on the popular singing competition program “The Voice” during the show’s fourth and sixth seasons. On the show, celebrity musicians coach up-and-coming amateurs in a team-based competition that eventually results in a single winner. In 2012, The Hollywood Reporter wrote that Shakira’s salary as a coach on “The Voice” was $12 million.

How does Shakira spend her money?

Shakira doesn’t just make a lot of money — she spends it, too. Like many wealthy entertainers, she’s purchased her share of luxuries, but Barranquilla’s barefoot belly dancer is also a prolific philanthropist, having donated tens of millions to charitable causes throughout her career.

Private island

Back in 2006, she teamed up with Roger Waters of Pink Floyd fame and Spanish singer Alejandro Sanz to purchase Bonds Cay, a 550-acre island in the Bahamas, which was listed for $16 million at the time.

Along with her two partners in the purchase, Shakira planned to develop the island to feature housing, hotels, and an artists’ retreat designed to host a revolving cast of artists-in-residence. This plan didn’t come to fruition, though, and as of this article’s last update, the island was once again for sale on Vladi Private Islands.

Real estate and vehicles

Like most wealthy celebs, Shakira’s portfolio of high-end playthings also features an array of luxury properties and vehicles, including a home in Barcelona, a villa in Cyprus, a Miami mansion, and a rotating cast of Mercedes-Benz vehicles.

Philanthropy and charity

Shakira doesn’t just spend her massive wealth on herself; the “Queen of Latin Music” is also a dedicated philanthropist and regularly donates portions of her earnings to the Fundación Pies Descalzos, or “Barefoot Foundation,” a charity she founded in 1997 to “improve the education and social development of children in Colombia, which has suffered decades of conflict.” The foundation focuses on providing meals for children and building and improving educational infrastructure in Shakira’s hometown of Barranquilla as well as four other Colombian communities.

In addition to her efforts with the Fundación Pies Descalzos, Shakira has made a number of other notable donations over the years. In 2007, she diverted a whopping $40 million of her wealth to help rebuild community infrastructure in Peru and Nicaragua in the wake of a devastating 8.0 magnitude earthquake. Later, during the COVID-19 pandemic in 2020, Shakira donated a large supply of N95 masks for healthcare workers and ventilators for hospital patients to her hometown of Barranquilla.

Back in 2010, the UN honored Shakira with a medal to recognize her dedication to social justice, at which time the Director General of the International Labour Organization described her as a “true ambassador for children and young people.”

On November 20, 2023 (which was supposed to be her first day of trial), Shakira reached a deal with the prosecution that resulted in a three-year suspended sentence and around $8 million in fines.

Shakira’s tax fraud scandal: How much did she pay?

In 2018, prosecutors in Spain initiated a tax evasion case against Shakira, alleging she lived primarily in Spain from 2012 to 2014 and therefore failed to pay around $14.4 million in taxes to the Spanish government. Spanish law requires anyone who is “domiciled” (i.e., living primarily) in Spain for more than half of the year to pay income taxes.

During the period in question, Shakira listed the Bahamas as her primary residence but did spend some time in Spain, as she was dating Gerard Piqué, a professional footballer and Spanish citizen. The couple’s first son, Milan, was also born in Barcelona during this period. 

Shakira maintained that she spent far fewer than 183 days per year in Spain during each of the years in question. In an interview with Elle Magazine, the pop star opined that “Spanish tax authorities saw that I was dating a Spanish citizen and started to salivate. It's clear they wanted to go after that money no matter what."

Prosecutors in the case sought a fine of almost $26 million and a possible eight-year prison stint, but in November of 2023, Shakira took a deal to close the case, accepting a fine of around $8 million and a three-year suspended sentence to avoid going to trial. In reference to her decision to take the deal, Shakira stated, "While I was determined to defend my innocence in a trial that my lawyers were confident would have ruled in my favour [had the trial proceeded], I have made the decision to finally resolve this matter with the best interest of my kids at heart who do not want to see their mom sacrifice her personal well-being in this fight."

How much did the Shakira statue in Barranquilla cost?

In late 2023, a 21-foot-tall bronze likeness of Shakira was unveiled on a waterfront promenade in Barranquilla. The city’s then-mayor, Jaime Pumarejo, commissioned Colombian sculptor Yino Márquez to create the statue of the city’s treasured pop icon, along with a sculpture of the city’s coat of arms.

According to the New York Times, the two sculptures cost the city the equivalent of around $180,000. A plaque at the statue’s base reads, “A heart that composes, hips that don’t lie, an unmatched talent, a voice that moves the masses and bare feet that march for the good of children and humanity.”

Those who have tried to book a flight from North America to Europe in the summer of 2023 know just how high travel demand to the continent has spiked.

At 2.93 billion, visitors to the countries making up the European Union had finally reached pre-pandemic levels last year while North Americans in particular were booking trips to both large metropolises such as Paris and Milan as well as smaller cities growing increasingly popular among tourists.

Delta Air Lines: ‘Glad to offer customers increased choice…’

By the end of March, Delta Air Lines  (DAL)  will be restarting its route between New York’s JFK and Marco Polo International Airport in Venice as well as launching two new flights to Venice from Atlanta. One will start running this month while the other will be added during peak demand in the summer.

More Travel:

“As one of the most beautiful cities in the world, Venice is hugely popular with U.S. travelers, and our flights bring valuable tourism and trade opportunities to the city and the region as well as unrivalled opportunities for Venetians looking to explore destinations across the Americas,” Delta’s SVP for Europe Matteo Curcio said in a statement. “We’re glad to offer customers increased choice this summer with flights from New York and additional service from Atlanta.”

The JFK-Venice flight will run on a Boeing 767-300  (BA)  and have 216 seats including higher classes such as Delta One, Delta Premium Select and Delta Comfort Plus.

Delta offers these features on the new flight

Both the New York and Atlanta flights are seasonal routes that will be pulled out of service in October. Both will run daily while the first route will depart New York at 8:55 p.m. and arrive in Venice at 10:15 a.m. local time on the way there, while leaving Venice at 12:15 p.m. to arrive at JFK at 5:05 p.m. on the way back.

According to Delta, this will bring its service to 17 flights from different U.S. cities to Venice during the peak summer period. As with most Delta flights at this point, passengers in all fare classes will have access to free Wi-Fi during the flight.

Those flying in Delta’s highest class or with access through airline status or a credit card will also be able to use the new Delta lounge that is part of the airline’s $12 billion terminal renovation and is slated to open to travelers in the coming months. The space will take up more than 40,000 square feet and have an outdoor terrace.

“Delta One customers can stretch out in a lie-flat seat and enjoy premium amenities like plush bedding made from recycled plastic bottles, more beverage options, and a seasonal chef-curated four-course meal,” Delta said of the new route. “[…] All customers can enjoy a wide selection of in-flight entertainment options and stay connected with Wi-Fi and enjoy free mobile messaging.”

Check back for updates throughout the trading day

U.S. stocks edged lower Thursday following a trio of key economic releases that have added to the current inflation puzzle as investors shift focus to the Federal Reserve's March policy meeting next week in Washington.

Updated at 9:59 AM EDT

Red start

Stocks are now falling sharply following the PPI inflation data and retail sales miss, with the S&P 500 marked 18 points lower, or 0.36%, in the opening half hour of trading.

The Dow, meanwhile, was marked 92 points lower while the Nasdaq slipped 67 points.

Treasury yields are also on the move, with 2-year notes rising 5 basis points on the session to 4.679% and 10-year notes pegged 7 basis points higher at 4.271%.

Updated at 9:44 AM EDT

Under Water

Under Armour  (UAA)  shares slumped firmly lower in early trading following the sportswear group's decision to bring back founder Kevin Plank as CEO, replacing the outgoing Stephanie Linnartz.

Plank, who founded Under Armour in 1996, left the group in May of 2021 just weeks before the group revealed that it was co-operating with investigations from both the Securities and Exchange Commission and the U.S. Department of Justice into the company's revenue recognition accounting.

Under Armour shares were marked 10.6% lower in early trading to change hands at $7.21 each.

Steely resolve

U.S. Steel  (X)  shares extended their two-day decline Thursday, falling 5.75% in pre-market trading following multiple reports that suggest President Joe Biden will push to prevent Japan's Nippon Steel from buying the Pittsburgh-based group.

Both Reuters and the Associated Press have said Biden will express his views to Prime Minister Kishida Yuko ahead of a planned State Visit next month at the White House.

Clear as mud

Retail sales rebounded last month, but the overall tally of $700.7 billion missed Street forecasts and suggests the recent uptick in inflation could be holding back discretionary spending.

A separate reading of factory inflation, meanwhile, showed prices spiking by 1.6%, on the year, and 0.6% on the month, amid a jump in goods prices.

U.S. stocks held earlier gains following the data release, with futures tied to the S&P 500 indicating an opening bell gain of 10 points, while the Dow was called 140 points higher. The Nasdaq, meanwhile, is looking at a more modest 40 point gain.

Benchmark 10-year Treasury note yields edged 3 basis points lower to 4.213% while two-year notes were little-changed at 4.626%.

Stock Market Today

Stocks finished lower last night, with the S&P 500 ending modestly in the red and the Nasdaq falling around 0.5%. The declines came amid an uptick in Treasury yields tied to concern that inflation pressures have failed to ease over the opening months of the year.

A better-than-expected auction of $22 billion in 30-year bonds, drawing the strongest overall demand since last June, steadied the overall market, but stocks still slipped into the close with an eye towards today's dataset.

The Commerce Department will publish its February reading of factory-gate inflation at 8:30 am Eastern Time. Analysts are expecting a slowdown in the key core reading, which feeds into the Fed's favored PCE price index.

Retail sales figures for the month are also set for an 8:30 am release as investors search for clues on consumer strength, tied to a resilient job market. Those factors could give the Fed more justification to wait until the summer months to begin the first of its three projected rate cuts.

"The case for a gradual but sustained slowdown in growth in consumers’ spending from 2023’s robust pace is persuasive," said Ian Shepherdson of Pantheon Macroeconomics. 

"Most households have run down the excess savings accumulated during the pandemic, while the cost of credit has jumped and last year’s plunge in home sales has depressed demand housing-related retail items like furniture and appliances," he added.

Benchmark 10-year Treasury yields are holding steady at 4.196% heading into the start of the New York trading session, while 2-year notes were pegged at 4.628%.

With Fed officials in a quiet period, requiring no public comments ahead of next week's meeting in Washington, the U.S. dollar index is trading in a narrow range against its global peers and was last marked 0.06% higher at 102.852.

On Wall Street, futures tied to the S&P 500 are indicating an opening bell gain of around 19 points, with the Dow Jones Industrial Average indicating a 140-point advance.

The tech-focused Nasdaq, which is up 7.77% for the year, is priced for a gain of around 95 points, with Tesla  (TSLA)  once again sliding into the red after ending the Wednesday session at a 10-month low.

In Europe, the regionwide Stoxx 600 was marked 0.35% higher in early Frankfurt trading, while Britain's FTSE 100 slipped 0.09% in London.

Overnight in Asia, the Nikkei 225 gained 0.29% as investors looked to a key series of wage negotiation figures from key unions that are likely to see the biggest year-on-year pay increases in three decades.

The broader MSCI ex-Japan benchmark, meanwhile, rose 0.18% into the close of trading.
