    How a failed experiment led to Einstein’s first big revolution | by Ethan Siegel | Starts With A Bang! | Aug, 2024

    The longer a photon’s wavelength is, the lower in energy it is. But all photons, regardless of wavelength/energy, move at the same speed: the speed of light. This is, surprisingly, irrespective of the motion of the observer relative to light; the speed of light is the same for all observers. (Credit: NASA/Sonoma State University/Aurore Simonnet)

    The Michelson-Morley experiment of 1887, despite expectations, revealed a null result: no effect. The implications were revolutionary.

    Imagine being alive in the late 1800s, and thinking about one of the most important physical phenomena in the Universe: light. A number of things that we take for granted today were already known about it. We knew that light:

    • moved at the speed of light, around 300,000 km/s,
    • exhibited wave-like behaviors such as interference and diffraction,
    • and was electromagnetic in nature, with oscillating in-phase electric and magnetic fields.

    We did make an underlying assumption about light, however, that wasn’t necessarily true: that, like all known waves, it required a medium to travel through. Just like water waves required the water, seismic waves required the Earth, and sound waves required the air to travel through, light was assumed to have a medium as well, known as the luminiferous aether.

    Since light was known to propagate through a vacuum — such as the vacuum of space that separated the Earth from the Sun — it never occurred to most that light didn’t need a medium to propagate through; it was…

  • TikTok Resorts to Cash Incentives to Attract New Users

    TikTok Resorts to Cash Incentives to Attract New Users

    [ad_1]

    It seems like TikTok has some significant concerns about its growth momentum, based on its latest efforts to lure new users.

    According to a report this week from The Information, TikTok has been looking to attract new users in the U.S. through a scheme that offers discounts when you invite friends from other apps.

    Creator economy expert Lia Haberman has also spotted this new promotion in the app, which outlines incentives for inviting YouTube and IG creators with big followings over to TikTok.

    TikTok incentive program

    As you can see, this new TikTok incentive program sees users rewarded with Amazon gift cards if they can get YouTubers with over 10k followers, and Instagram users with 100k, to sign-up to TikTok as well.

    Which seems a little desperate, and a little like TikTok is running out of ideas for growth, given that it’s resorting to cash rewards and discounts to get more users across.

    And that may well be the case, with various reports suggesting that TikTok’s growth has plateaued, and is even declining in some regions. The short-form video app rocketed to a billion users back in 2021, but since then, it’s provided no official update on its active user count. External reports suggested that TikTok would surpass 1.5 billion users in 2022, but amid restrictions in certain regions (most notably India) and other challenges, TikTok never officially announced this number, and hasn’t reported much on its growth ever since.

    Though looking at the data that it has reported, it’s fairly clear that it’s lost some of its growth momentum.

    In the U.S, where TikTok is also staring down a ban, TikTok currently has 170 million users, rising from the 150 million that it reported in March 2023, while in Europe, its DMA disclosures show that TikTok added just 6 million users between October 2023 and April 2024.

    So TikTok’s meteoric rise has clearly eased, and these new programs would suggest that it’s declining even more over time. Which is logically why it now feels the need to pay people to come try the app, in the hopes of reigniting user interest.

    TikTok has tried similar in Europe, with its “TikTok Lite” program offering incentives for ongoing TikTok usage.

    TikTok Lite

    As you can see in this example, the explainers here (in French) inform users that they can earn points by discovering and liking videos in the app.

    TikTok had launched the program in France and Spain on a limited basis, before it got the attention of EU officials, who raised concerns that the scheme may violate the DSA. TikTok has now canceled the initiative, for fear of EU fines. But again, its very existence carries a hint of desperation, of a platform that’s slowly losing its grip, and is concerned about its ongoing relevance and resonance.

    To be clear, TikTok is still hugely popular, but data privacy concerns do seem to be keeping some users away. Add to that the rising popularity of Instagram Reels and YouTube Shorts, and its key value proposition has been diluted significantly, with both apps also offering expanded following and engagement options to incentivize creators.

    As such, while it does still have a billion users, TikTok is at risk of losing out. And if it is banned in the U.S., as currently looks to be the case, that could be a big blow for its growth ambitions, and its future in other markets.

    The U.S. removal threat also means that TikTok is not currently a stable base for creators, which would be another reason why they’re staying away. And a $300 Amazon gift card is unlikely to change that,  which points to future concerns for the platform, again, if the U.S. sell off push does go through as expected.

    So while TikTok is a key app at present, you can see why it’s growing increasingly concerned about its opportunities. Its removal in the U.S. would see a heap of its top creators immediately removed from the app, which could then see it lose ground very quickly, hence the need to address it now, before it’s too late.

    But I’m not sure that there’s anything that TikTok itself can do here, other than challenge the U.S. sell off bill (which it’s doing).

    Essentially, TikTok is in a bit of a holding pattern till we know for sure whether the U.S. sell-off bill will definitely be enacted. And till then, TikTok’s future will hang in the balance, and not just in the U.S.

    It seems crazy that a billion-user platform could be at such high risk, but a congregation of unique factors is clearly heaping pressure on the business.

  • Kamala Surges in Battleground States

    Kamala Surges in Battleground States

    [ad_1]

    It’s a new ballgame.
    Photo-Illustration: Intelligencer; Photos: Getty Images

    The sharp improvement over Joe Biden’s position in the national popular-vote polls that Kamala Harris has achieved since the Great Switcheroo of July 21 has justifiably gotten a lot of attention. After all, in today’s hyper-polarized environment, a six-point swing from a race where Trump was leading Biden (per the FiveThirtyEight averages) by 3.2 percent nationally to one where Harris is leading Trump by 2.9 percent is a very big deal, reflecting a big uptick in Democratic enthusiasm and a significant drop in the “double hater” vote (and correspondingly, in Robert F. Kennedy Jr.’s support).

    But as we were reminded in the Republican victories of 2000 and 2016, and Donald Trump’s near-miss in 2020, presidential elections are decided in the Electoral College rather than the popular vote, which national polls estimate. And Kamala Harris’s most significant accomplishment in the last three and a half weeks has been to climb into a highly competitive position with Trump in the seven battleground states where the deal will ultimately go down.

    To be clear, Biden’s chronically poor performance in five of these states was a big part of the panic afflicting Democrats even before his terrible debate performance on June 27 and subsequent waffling over withdrawal. On the day Biden did fold his tent (July 21), in the FiveThirtyEight averages Trump was leading him by 5.5 percent (45.0 to 39.5 percent) in Arizona; by 5.8 percent (44.3 to 38.6 percent) in Nevada; by 5.9 percent (45.1 to 39.2 percent) in Georgia; by 6.9 percent (45.6 to 38.7 percent) in North Carolina; and by 4.4 percent (45.5 to 41.1 percent) in Pennsylvania. Biden was also trailing Trump in Michigan (42.4 percent to 43.8 percent) and Wisconsin (42.2 to 44.5 percent), but by smaller margins, which convinced most observers that Biden’s narrow path to 270 electoral votes was via a sweep of the Rust Belt “blue wall” states. This in turn fed the obsession in some circles with Biden’s weakest “blue wall” state, Pennsylvania, which was reflected in the punditry consensus that Harris ought to choose Keystone State governor Josh Shapiro as her running mate.

    But at present Harris is in a very different position in the battleground states. There hasn’t been enough recent polling in North Carolina for FiveThirtyEight to conduct averages, but she leads Trump in five of the other six crucial states: in Arizona by 0.7 percent (45.3 to 44.6 percent); in Georgia by 0.1 percent (45.8 to 45.7 percent); in Michigan by 3.4 percent (46.3 to 42.9 percent); in Wisconsin by 3.6 percent (47.4 to 43.8 percent); and yes, even without Josh Shapiro on the ticket, in Pennsylvania by 2.2 percent (46.4 to 44.2 percent). Trump is hanging onto a 0.1 percent lead (44.5 to 44.3 percent) in Nevada.

    So the Blue Wall is looking reasonably solid, and more importantly, Harris has regained a competitive position in the Sun Belt battlegrounds, with the race basically tied in three of Biden’s weaker states (Arizona, Nevada, and Georgia). Strategically, this makes all the difference in the world, since Harris now has multiple paths to 270 electoral votes. Underlying this Sun Belt recovery is Harris’s superior strength among younger, Black, and Latino voters. An August 2 likely voter survey from CBS-YouGov showed Harris at over 60 percent among under-30 voters, and over 80 percent among Black voters. And a large-sample survey of Latino voters in Arizona, Nevada, Pennsylvania, Michigan, Wisconsin, Georgia, and North Carolina in late July from BSP Research shows Harris leading Trump by a robust 55-37 percent, a margin almost exactly replicated in an early August battleground state Latino survey from Equis. It’s definitely a whole new ball game with an expanded battleground map.

    It’s worth noting that in two crucial battleground states, Arizona and Nevada, Harris and other Democrats may get a boost from newly certified ballot initiatives to protect abortion rights. These initiatives will help keep voters focused on partisan differences over abortion rights, and could produce a beneficial turnout surge among voters likely to lean Democratic. Limited polling has showed the Arizona initiative being favored by about 2-1, with even higher support for the initiative in Nevada.

    There are competitive U.S. Senate races in five presidential battleground states: Arizona, Nevada, Michigan, Pennsylvania, and Wisconsin. According to the RealClearPolitics polling averages (FiveThirtyEight is not offering averages for Senate races at this point), the Democratic nominees are leading in all of these races. In Arizona, Ruben Gallego leads Kari Lake by 3.4 percent (47.0 to 43.6 percent); in Nevada, Jacky Rosen leads Sam Brown by 4.0 percent (46. 7 to 42.7 percent); in Michigan, Elissa Slotkin leads Mike Rogers by 5.4 percent (46.4 to 41.0 percent); in Pennslyvania, Bob Casey leads Dave McCormick by 6.8 percent (49.4 to 42.6 percent); and in Wisconsin Tammy Baldwin leads Eric Hovde by 6.1 percent (50.1 to 44.0 percent). In fact, the Democrats have led in every published poll of these races so far. None of the Democrats in these contests are distancing themselves from the national ticket — indeed, some are much warmer toward Harris than they were toward Biden. That means presidential and Senate campaigns will be closely coordinated, and, they hope, mutually reinforcing as Democrats continue their upward trajectory.

    The Hundred: Southern Brave through to eliminator at the Kia Oval on Saturday as rain thwarts Welsh Fire | Cricket News

    [ad_1]

    Southern Brave secured their place in The Hundred men’s eliminator at the Kia Oval on Saturday after rain intervened at Utilita Bowl against Welsh Fire.

    Brave came into the match knowing that a point would guarantee their presence in Saturday’s showdown but at the halfway stage, with 181 posted by already-eliminated Fire, they would have feared losing control of their destiny.

    Two quick wickets – Alex Davies for a duck and then James Vince for 19 – further set Brave back. But following Vince’s dismissal, with rain falling steadily, the umpires took the players off.

    The rain never abated and with just 16 balls having been bowled of Brave’s innings – a minimum of 25 balls are required to deliver a result – the game was duly abandoned.

    It was a bitter pill for Fire to swallow. With the bat they were irrepressible, with Luke Wells and Glenn Phillips especially destructive, sharing a 76-run partnership from just 30 balls to propel Fire to their highest-ever score in the tournament.

    Wells registered just his second fifty in the competition while Phillips clubbed five sixes – including one hit over square-leg against Jofra Archer that sailed 102 metres – to make 48 from just 19 balls.

    For Brave, only Akeal Hosein escaped punishment, the West Indian left-armer conceding just 21 from his 20-ball quota.

    Ultimately, it was immaterial. Brave are through to face either Oval Invincibles, Northern Superchargers or Birmingham Phoenix, with the latter’s game against Manchester Originals on Thursday determining the final placings at the top.

    Player of the match- James Vince

    “Bowling first, things probably got away from us a bit. We were sloppy. Some good players got going and we weren’t able to shut them down, so it was always going to be a tough ask to chase that down,” said Vince.

    “We had a few messages saying the weather might be on its way so we had a few discussions about how to approach those first 25 balls; thankfully the rain came just in time.

    “On the whole, across the tournament, the bowling group gets a lot of credit. They’re quality, experienced bowlers. Our batting goes under the radar a bit. We’d like a few more guys in form, but on the whole we’ve been reasonably consistent.”

    The Oval Invincibles encountered a number of errors that may have cost them against the Trent Rockets

    Trent Rockets claimed a consolation home win over Oval Invincibles thanks to a spectacular display of hitting from Rovman Powell.

    Coming to the crease with 95 needed from 52 balls and the Rockets three wickets down, Powell joined Tom Alsop in an 80-run stand to take the Rockets towards the Invincibles’ total of 150.

    Powell hit four sixes, with one off Sam Curran going 101 metres, before the England man induced Powell to miscue a lofted drive to long-on.

    The Jamaican’s dismissal left the Rockets needing 15 from 10 balls, but Alsop and Chris Green took the home side to victory with six balls to spare.

    Rovman Powell hits four enormous sixes during his innings

    Choosing to bat first on a pitch taking turn, Invincibles opener Dawid Malan made a composed half-century, batting through the innings for an unbeaten 53 (43) to allow the hitters to open up around him.

    Will Jacks’ quickfire 30 came from 17 balls, before Jordan Cox smashed a 30-ball 39 in a 71-run partnership with Malan.

    Cox succumbed to Sam Cook, whose figures of 2-23 were the most economical of the Rockets’ bowlers, but Donovan Ferreira’s unbeaten 27 from just 10 balls featured three successive sixes and hauled the Invincibles up to 150-3.

    Saqib Mahmood, bowling 15 of the first 20 balls of the Rockets innings, was fast and hostile, regularly touching 88mph and accounting for the wicket of Tom Banton in his opening spell.

    Alex Hales, on 35, misjudged a pull to give Jacks his first wicket, and Joe Root lofted a Nathan Sowter leg-break to long-on for 12 to leave Trent 56-3 after 48 balls.

    But Powell and Alsop then took charge as the hosts won with six deliveries to spare.

    Invincibles will now await the result of the final group game on Thursday to discover whether they will contest the Eliminator at the Oval or go straight through to Sunday’s final at Lord’s.
