Why aren’t there solar-powered cars?

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to curiouskidsus@theconversation.com. Why aren’t there solar-powered cars? – Emma, age 16, Springville, Utah Solar cars exist. The best place to see them is the World Solar Challenge, a race that’s held every two years in Australia. Competitors have to drive about 1,870 miles (3,000 kilometers), from Darwin on the country’s north coast to Adelaide on its south coast, using only energy from the Sun. Many cars that compete in this race look more like amusement park rides or science fiction vehicles than the cars you see on the road. That tells you something about why solar cars aren’t an option for everyday travel, at least not yet. Collecting enough sunlight While a lot of sunli...

God’s Providential Plan for Us Embraces Everything We Do — Even Politics…

God’s purposes are often unknowable by us, but there’s no question that he has a plan. A chorus of populist theologizing greeted the attempted assassination of Donald Trump. Much of it was along the lines of “Considering that the shot missed killing him by only a couple of inches, God must have been looking out for him.” I fully agree. God certainly was looking out for the former president. So what else might we say about what happened? Although pushing too hard to explain God’s ways can be presumptuous, we can at least say that any serious attempt to understand will run up against mystery. Comprehending God’s plan in its literally unimaginable extent and complexity lies far beyond our limited capacity for grasping divine realities other than those he reveals. As for the little that we do ...

The Congress, the Olympics, and cocaine sharks Skip to content Pillar subscribers can listen to JD read this Pillar Post here: The Pillar TL;DR Hey everybody, Today is the 16th Wednesday in Ordinary Time, and you’re reading The Tuesday Pillar Post. If you’re not sure why you’re reading The Tuesday Pillar Post on Wednesday, well, I sent you a note about it yesterday. But the long and short of it is that Ed’s on vacation this week, I’ll be on vacation next week, and so we’re doing things a bit differently to adjust to being short-staffed. There will be a podcast this week, albeit without Ed, and I believe he’ll aim to make one next week as well.  Anyway, as you probably know, the 2024 Paris Olympics kick off in just two days, and will probably begin with some bit of avant garde made-for...

How the Ancient Christians Can Give You Hope and Teach You to Spread the Faith…

In times like these, it’s easy to despair about evangelization in the modern world. But a new Ignatius Press book by Mike Aquilina, Rabbles, Riots, and Ruins: Twelve Ancient Cities and How They Were Evangelized, not only offers some much-needed hope when thinking about evangelizing today’s culture but also serves as a guide on how to go about it. The Register caught up with the book’s author at his home in Pittsburgh and asked if Christian hope can persist amid the despair of modern Western cities. “Absolutely,” replies Aquilina. “Was there any earthly reason to hope in the midst of the Decian persecution? I can’t see any. The Romans mobilized as a police state for the eradication of Christianity. In the natural order, the world was falling apart, because of severe climate change and resul...

‘Brethren, What Shall We Do?’…

“Brethren, what shall we do?” (Acts 2: 37) Such was the response of “devout men from every nation under heaven” (Acts 2:5) to St. Peter’s Pentecost Discourse. The Holy Scriptures tell us that “that they were cut to the heart” (Acts 2:37). St. Peter had proclaimed to them the truth of the Redemptive Incarnation with these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs which God did through Him in your midst, as you yourselves know — this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. But God raised Him up, having loosed the pangs of death, because it was not possible for him to be held by it.… This Jesus God raised up, and of that we all are witnesses. Being th...

J.D. Vance is a Catholic ‘post-liberal.’ Here’s what that means — and why it matters…

J.D. Vance is an election away from becoming the first Catholic vice president from the Republican Party. But the Ohio senator, who is running alongside Donald Trump on the GOP ticket, is not your typical Catholic conservative — at least not the kind that has been the norm in American politics over the past half-century. Instead, Vance is a self-described member of the “post-liberal right,” an upstart political movement that flips the conventional conservative script and emphasizes the good of the community over individual liberty. The controversial approach, which is both inspired by and contested within the Catholic Church, includes harnessing state power to secure its aims, another break from the standard operating procedure of the American right. And if Vance is elected vice president,...

The Hard Reality of Disagreement in Marriage…

Open disagreement between spouses, or even just not seeing eye to eye, can be very painful. It is also quite common. Central to the art of marriage is to be able to accept this while also addressing it. Experience shows that it is to be expected. To some extent then, disagreement need not mean that anything has gone wrong. We do well to begin by recognizing that how we deal with disagreement is precisely a key feature of how we grow our marriage and as individuals; I’d even go so far as to say it is ‘natural’ and part of the plan. This should be a very heartening thought. Of course certain deeper disagreements might cross a line of seriousness and call for intervention or other such remedies. But most of us will be within a range of discord, variance, or tension that is ‘normal,’ the addre...

Here’s the Early 20th-Century Catholic Modernist Crisis in a Nutshell…

Josephine Hope-Scott Ward (1864–1932) wrote at the crossroads of the implementation of Catholic Emancipation in England—particularly the Universities Tests Acts of 1871—and the Catholic Modernist Crisis (1893–1914). The author of ten novels, a novella, and numerous articles and personal writings, Josephine Ward’s body of work provides a unique look into how the modernist controversy was experienced by English Catholics in the first decade of the twentieth century. Josephine Ward was the niece of the Duke of Norfolk, which demonstrates her ties to Recusant England. She was also the daughter of the Tractarian and Oxford convert, James Robert Hope-Scott (1812–1872). In 1887, Josephine married Wilfrid Ward (1856–1916), who was the son of the notable Oxford convert, William George Ward (1812–18...

The National Eucharistic Congress Provided a Reprieve and a Chance for Catholics to See Politics Differently…

For the past few weeks, the world of U.S. politics has seemed especially contentious and unstable, with an overabundance of supercharged storylines producing a new wave of anxieties and raising the political temperature. But as the political drama continues, 50,000 Catholics in Indianapolis and thousands more following the National Eucharistic Congress (NEC) from afar seem unphased, their attention decidedly not on partisan politics, but on the source and summit of their faith. “I doubt there is any place in the nation so untroubled by our tumultuous politics right now as the attendees at the Eucharistic Congress,” Stephen White, the director of The Catholic Project at The Catholic University of America, told the Register from Indianapolis. “Not because people here are indifferent to polit...

The Knights Got It Right With Marko Rupnik’s Art…

The opaque fabric will rest on the chapel walls of the Saint John Paul II National Shrine in Washington, D.C., like a dressing on a wound. It’s a fitting image, since the artwork beneath that material has, for many, become a symbol of grave harm — in what ought to be places of hope and healing. The announcement July 11 that the Knights of Columbus will, for the time being, cover over its mosaics by Father Marko Rupnik at the shrine’s two chapels, as well as the chapel at the organization’s headquarters in New Haven, Connecticut, marks a possible turning point in the ongoing scandal surrounding the disgraced Slovenian priest. Whether it will prompt shrines like Lourdes and other Catholic institutions around the world to do the same with their works by Father Rupnik remains to be seen. Just ...

4 Notable Christian Dimensions of the Trump Assassination Attempt…

Editor’s Note: The caption was updated to explain the background of the misspelling on the uniform jacket shown in the photo. The attempted assassination of former president Donald Trump Saturday has far-reaching personal and political consequences. Many commentators took it as a worrying indicator of the state of U.S. culture, or at least political culture.  Yet beyond the personal, political and cultural, there were also notable Christian dimensions to that terrible evening in Butler, Pennsylvania. Four are worth noting. Reading Providence It is not unusual for any near brush with death to prompt reflections on why a life was spared, often considered to be “miraculously” spared. When prominent people are involved, that reflection is more widespread. And so, after President Trump sur...
