  • Monaco GP: Martin Brundle salutes ‘unbeatable’ Kimi Antonelli, gives verdict on speeding penalties in F1 race

    Sky Sports F1’s Martin Brundle gives his verdict on Kimi Antonelli’s dominant Monaco GP victory, along with the race’s contentious pit-lane speeding penalties;

    F1 fans have often said to me, ‘we are thinking of going to Monaco, where should we get a grandstand seat and isn’t race day all about follow the leader?’

    I have to point out I don’t know as I haven’t sat in a grandstand seat for over 40 years because I’m in the pits and commentary boxes, but do advise them to fully absorb the sights, sounds, and incredible atmosphere, and enjoy all track running on Friday and particularly qualifying on Saturday, usually the best of the year, and hope to get lucky on Sunday for a good race.

    This year’s race gave us a full house as far as I’m concerned. The weather was great, qualifying was a last driver over the line cliff-hanger, and then one of the more chaotic races unfolded on Sunday, which was still playing out more than two hours after the chequered flag.

    It’s rare that I feel the need to study the official final classified results to be sure of who finished where having just talked about it uninterrupted for two and a half hours, but I did on this occasion.

    Kimi Antonelli made less mistakes than all the other front runners despite his relatively limited experience, and claimed pole position in sensational style. As race day would demonstrate too, he has found an overdrive for even more speed and is totally at one with his car and team. I thought he’d make mistakes here and clout the barrier at some point, but he was committed yet precise and controlled.

    The grid was bustling as always and informative too in different ways, but all thoughts were on the short dash to the first corner. Kimi had Max Verstappen to his left who’d done a tremendous job in qualifying in his Red Bull on the front row.

    Behind him were the two fast starting Ferraris of Lewis Hamilton and Charles Leclerc, surely this would be big pressure for the teenager?

    Not a bit of it, he made the perfect start, didn’t lock his front brakes into the first corner, and then dominated the race, building a half-minute lead before the safety car was called when Lance Stroll crashed in the final turn on lap 60 of 78.

    Antonelli just missed the pit entry and so pitted on lap 61 but comfortably retained the lead, which of course was diminished with the two Ferraris and the rest of the pack catching him right up behind that Safety Car.

    Speeding penalties necessarily brutal’

    There was a significant sub-story to this whole race, that of speeding in the pit lane. A few drivers had fallen foul of that even just doing their reconnaissance laps to the grid. It was a situation which had been noted between the race director and teams during practice too.

    Pit-lane speed is measured by distance between various loops in the track surface, and as always drivers were finding a way to cut into the pits slightly early to save a metre or two. Because of the tight confines, the speed limit in Monaco is reduced from 80 kph to 60 kph. Despite doing everything right drivers were being penalised for 60.1 kph. Rules are rules because if that’s fine, then 60.2 is only a fraction more and so must be fine too. Just like when a car is half a kilo underweight, in F1 it’s necessarily brutal.

    There were many of these tiny infractions, including manageable five-second penalties for Hamilton and Oscar Piastri. But it would ruin George Russell’s race because during his pit stop under the Safety Car, the Mercedes team were obliged to serve his five-second speeding penalty before commencing a tyre change, and at the same time all cars were obliged to come through the pit lane to allow the crashed car in the last corner to be cleared.

    There was confusion as he queued up behind his teammate and he would receive an effective 20-second drive-through penalty, which would put him at the back of the bunched-up field. A critical podium chance was lost but I have no doubt George will return to form and luck.

    It was arguably even more painful for Pierre Gasly in his Alpine who was both infuriated and heartbroken to receive two pit-lane speeding penalties 20 minutes apart, for 60.1 kph and 60.4 kph. He would cross the finish line in third place which would normally mean a trip to the legendary royal podium, but 10 seconds of penalties would demote him to seventh through no fault of his own. The team have demanded a right of review, but I suspect that’ll change nothing.

    ‘Antonelli sealed win in superb style’

    ‘Safety Cars create Safety Cars’ is an old saying and on the first Safety Car restart local hero Leclerc would crash into the same barrier as Stroll on the final corner of the lap and retire on the spot. He remains convinced it was all about enduring brake problems, but the track was also breaking up on the way into that corner, such that a race halting red flag was shown so that race control could head out and inspect the asphalt.

    After a couple of passes with a sweeping machine and a bit poking around, it was declared there’d be a restart with a couple of sighter laps behind the Safety Car and then a standing restart on the grid, as is now normal unless conditions and visibility are poor.

    Now Antonelli would have Hamilton, who had been going along nicely all race in second place beside him on the front row. Once again, the young Italian launched perfectly and simply checked out again up front. The youngest ever winner of the Monaco Grand Prix would claim his fifth straight victory in superb style, he really was in a class of one around the Principality, with pole position, fastest lap, and leading every lap. He’s just getting better and better…

    Hamilton’s second place was timely and poured salt into Russell’s wounds as it moved the Ferrari driver up to second in the world championship.

    One of the biggest disappointments of the race was Verstappen not getting away properly from the very original start 143 minutes earlier. He would retire at the end of the first lap, and we were all robbed of the chance to watch him try every trick in the book to pass Antonelli in the early stages, assuming he could keep up of course.

    Hadjar impresses on ‘wild Monaco weekend’

    In the sister Red Bull, Isack Hadjar would inherit Gasly’s final podium spot after a sterling drive despite carrying power unit issues along with many angsty radio calls. He also survived two stewards’ enquiries for potential Safety Car and red-flag infringements, the latter when the team began to do disallowed work on his car before ceasing that procedure. It was a great drive from Isack.

    Piastri would come home fourth having had that speed limit penalty, but with very little raw speed out on track. It was a painful day for McLaren having also lost Lando Norris with a second consecutive retirement due to power unit issues. The team still feel confident about upcoming improvements and races.

    Liam Lawson told me pre-race that his car would likely not be fixed in time and his best-case scenario was a pit-lane start. He did though make the grid and came home in a very fine fifth place. He was backed up by rookie team-mate Arvid Lindblad in an equally fine sixth place winning a total of 18 points for what is currently a very cohesive Racing Bulls team.

    There were five post-race penalties, one of which was for Sergio Perez in his Cadillac, which provisionally had scored their first ever championship point. Bizarrely Sergio had two start line penalties, on the original grid he started 16th instead of 18th as Gabriel Bortoleto was forced to start his Audi from the pit lane after it stalled during a practice start, and so he was absent from 16th on the grid in front of Sergio’s proper slot.

    On the second start after the red flag, Perez was slightly right of his grid slot and took a further penalty, relegating him to 15th of 16 finishers.

    Nico Hulkenberg was also in the points for Audi but he took a post-race penalty for collecting the back of Carlos Sainz’s Williams in a scrum at the hairpin. It was harsh but inevitable due to precedents. Nico ended up 13th.

    Sainz was eliminated, which is a shame because Williams looked on for a double points finish after using both of their cars in sync to help build pit stop gaps by slowing the pack behind down. Alex Albon would at least finish in the points in eighth.

    Esteban Ocon was ninth but I don’t remember seeing much of him in the race, and through the barrage of penalties came the relentless Mr. Fernando Alonso scoring Aston Martin’s first point of the season. I doubt he threw a big party though.

    The Stewards handled 30 cases and the final results were issued just before 9pm. That was one very wild Monaco Grand Prix weekend, and Kimi Antonelli was serene and unbeatable throughout.

  • 涨价比黄金和石油还厉害!这样东西就在你的手里

    近日,有人发现,去年花 400 多元买的移动固态硬盘,现在要花 800 多元才能买到!涨价幅度堪比黄金!

    事实上,不只是硬盘,还有 U 盘、相机存储卡、电脑内存条等设备,在今年的价格都涨到了原来的三四倍,涨价幅度堪称“疯狂”。

    涨价的根源,就来自——存储芯片。

    啥是存储芯片?

    大家对芯片这个词都很熟悉。它有很多不同的功能分类,而和我们日常使用电子设备最息息相关的,主要是两大核心类型。

    一类是逻辑芯片,就是我们经常在新闻上看到的 2 纳米、3 纳米、5 纳米等先进制程芯片。它是电子设备的“大脑”,主要集成在中央处理器(CPU)、图像处理器(GPU)等核心组件中。

    另一大类就是存储芯片。它是电子设备的“仓库”,核心使命是稳定、持久地保存二进制的 0 和 1 数据,不承担通用运算任务。我们能在平时使用的设备里留存多少文件、多少内容,核心就取决于设备中存储芯片的容量。

    存储芯片还可以分为两大家族:

    闪存(NAND Flash):它的特点是“永久记忆”,就像一个仓库,功能是帮你保存重要数据,断电后数据也能长期保存。

    内存(动态随机存取存储器,DRAM):它是给 CPU、GPU 等计算单元提供临时计算空间的,特点是读取速度极快,但“断电即忘”,关机了数据也就没了。

    以实际例子说明:我们买手机、电脑时,能看到内存和存储空间的各种组合,比如 8G+256G、16G+512G,前面的 8G、16G 表示内存,后面的 256G、512G 表示存储空间。

    而用来给电脑拷文件的 U 盘、移动固态硬盘,参数会写容量 1T、2T,这就单纯是闪存而非内存,只用来存储数据,不用来进行计算。

    为什么大涨价?

    芯片涨价最主要的因素有三个:行业供求关系、AI 大模型,以及成本上涨。

    第一个原因是,存储芯片的生产厂商正在集体缩减传统低端存储产品的产能。

    此前,受消费电子需求崩盘、厂家扩产产能集中释放的影响,存储芯片的价格曾跌到谷底,整个存储行业都遭遇了严重的亏损。为了自救,厂商集体“断臂求生”,选择大幅减产去库存。产量一降,库存见底,价格自然在此后水涨船高。

    如今厂家对传统低端存储的扩产都非常谨慎,宁愿保持高价慢慢卖,也不想再回到当年疯狂增产、进而导致全行业亏损的惨状。

    其次,AI 大模型的狂飙发展,彻底改变了存储芯片的产能结构。

    大模型在训练时,除了需要高性能的 GPU,还需要一种极其高端的内存:高带宽内存(HBM)。为了在大模型更新换代的激烈竞争中抢占身位,AI 厂商直接高价竞购 HBM,各大存储行业巨头自然也迎合需求,一股脑都将核心产能大幅转向 AI 相关的高端存储芯片。

    随之而来的,是存储厂商减少生产各种普通的存储芯片,稀缺催生了高价。甚至不光是依赖存储芯片的固态硬盘、内存大涨,就连不靠芯片存数据的机械硬盘,也因为产能被芯片行业挤压、配套元器件涨价,市场价跟着暴涨。

    最后,原材料与运输成本也在不断上涨。

    在过去一年里,制造存储芯片所需的特殊化学品和晶圆原料的成本上涨明显。尤其是近期霍尔木兹海峡航运受限,大量生产芯片的原材料(比如氦气)无法运出,进一步导致生产成本居高不下。

    涨价涨到什么时候?

    这波涨价到底是暂时的,还是会持续很长时间?

    分析普遍认为,存储设备的价格可能在 1-2 年内都会保持在高位。关键问题在于,存储设备这个产业本身存在一个 1-2 年的滞后周期:

    从生产端看,在 2022 年-2024 年的价格暴跌中,全球头部存储厂商不仅大幅度减产,还大砍了 2025-2026 年的开支和扩产计划。同时,生产线的建设需要设备采购、良率测试等非常漫长的过程,完整的周期就需要 1-2 年。

    从需求端看,AI 行业巨头会持续吃掉未来 1-2 年几乎所有新增存储产能,普通人需要的手机内存和电脑硬盘的生产空间自然也就会被压缩。同时电子设备的存储容量都在翻倍升级,比如手机从 128G 起步升级为 256/512G起步,存储需求大幅提升,自然导致电子产品价格上涨。

    综上所述,建议就是,有刚需就买,非必需消费就再等一轮周期。

    不吃霉变食物,不嚼槟榔

    霉变的花生、玉米等,极易产生黄曲霉毒素,这是公认的1类致癌物,毒性极强,长期摄入会大幅提升肝癌风险。

    槟榔及槟榔制品同样被列为1类致癌物,长期咀嚼会持续损伤口腔黏膜,是口腔癌、咽癌、食管癌的重要诱因。

    建议:一旦食物发霉,哪怕只坏了一部分,也建议整份丢弃。为了健康,一定要远离槟榔及其制品。

    不吃过烫食物,饮品放温再喝

    65℃以上的热饮被列为2A类致癌物。刚出锅的饭菜、滚烫的茶水、热汤,都会灼伤消化道黏膜。长期反复刺激,会让食管上皮细胞异常增生,增加食管癌风险。

    建议:吃饭别心急,喝水别贪烫,等温度适宜再入口,才是安全的饮食习惯。

    少吃腌制、熏烤、油炸及加工肉

    咸菜、腊肉、烧烤、油炸食品,虽然风味十足,却暗藏健康隐患。腌制食品中的亚硝酸盐,可能增加胃癌、鼻咽癌风险;

    熏烤和高温油炸食物会产生多环芳烃等致癌物,提升结直肠癌风险;

    火腿、香肠、培根等加工肉制品,也被证实与结直肠癌风险升高相关。

    建议:日常饮食尽量以新鲜食材为主,多采用蒸、煮、快炒等健康烹饪方式,少吃重口味加工食品。

    少碰甜食,拒绝含糖饮料

    蛋糕、奶茶、糖果等高糖食物,不仅让人发胖,还会间接推高癌症风险。超重和肥胖与乳腺癌、结直肠癌、胰腺癌等多种癌症相关。长期高糖饮食还可能诱发2型糖尿病,进一步增加肝癌、胆囊癌等患病可能。

    建议:戒掉含糖饮料,少吃甜点,控制添加糖摄入,清淡饮食才更健康。

    多吃蔬果、全谷物,补足膳食纤维

    新鲜蔬菜和水果富含维生素、膳食纤维与抗氧化物质,能降低口咽癌、肺癌、胃癌等风险。全谷物则有助于降低乳腺癌、结直肠癌的风险。

    建议:《中国居民膳食指南(2022)》指出,成年人每天吃够蔬菜300~500克、水果200~350克,主食中搭配50~150克全谷物和杂豆,营养均衡,防癌效果更佳。

    少饮酒、不酗酒,能不喝就不喝

    酒精中的乙醇及其代谢产物乙醛,均为1类致癌物。饮酒会直接损伤消化道黏膜,增加头颈癌、食管癌、肝癌等风险。

    建议:最安全的方式,就是不饮酒。

    防癌要活动“身体”

    久坐、肥胖是危险致癌因素

    控制体重,管理腰围

    肥胖是一种慢性炎症状态,会扰乱激素平衡,为癌细胞创造“温床”。

    建议:BMI控制在18.5~24;男性腰围<90厘米,女性腰围<85厘米。

    △图自《中国防癌健康生活方式守则》

    坚持运动,减少久坐

    久坐已被证实与乳腺癌、结直肠癌等风险升高相关。而规律运动能增强免疫、减轻炎症,缩短致癌物在肠道停留时间,有效防癌。

    建议:每周至少进行150分钟中等强度运动(快走、慢跑、游泳、骑车)或75分钟高强度运动。同时,别小看日常活动:爬楼梯、走路通勤、做家务,都在帮你远离癌症。

    防癌要远离“癌源”

    避开这些隐藏的致癌因素

    注意个人卫生,分餐用公筷

    幽门螺杆菌、乙肝病毒、丙肝病毒、EB病毒等都是通过唾液、血液等途径传播,与多种癌症的发生密切相关。

    建议:养成良好的个人卫生习惯,如聚餐时使用公勺公筷、注意餐具清洁消毒以及避免食用不洁食物,避免共用牙具、剃须刀等。

    避免暴晒,做好防晒措施

    紫外线为1类致癌物,长期或过度暴露于紫外线可增加皮肤癌的发生风险。

    建议:阳光强烈时,出门应做好防晒措施,例如涂防晒霜、戴帽子、打伞、穿防晒衣等。

    保持通风,减少空气污染

    多种空气污染物与癌症发生密切相关。室外空气污染、二手烟、室内装修释放的甲醛和苯,都是1类致癌物。

    建议:雾霾天减少外出,出门戴口罩;家里不吸烟,做饭开抽油烟机,装修选择环保材料;空气质量好时,记得开窗通风。

    做好职业防护,远离致癌物

    如果从事化工、油漆、家具制造、建筑拆除、电镀、焊接等行业,可能接触到苯、甲醛、石棉等职业性致癌物。

    建议:正确佩戴防护装备,下班后及时更衣、洗澡,把风险降到最低。

    防癌要科学“防护”

    这2个防癌疫苗要知道

    两个防癌疫苗要知道

    乙肝疫苗:乙肝病毒感染是导致肝癌的主要原因之一。接种乙肝疫苗是预防最有效的手段,新生儿和未接种的成年人都建议接种。

    HPV疫苗:高危型人乳头瘤病毒(HPV)持续感染可导致宫颈癌、口咽癌、肛门癌等。适龄人群尽早接种HPV疫苗,越早接种,保护效果越好。

    母乳喂养降低乳腺癌风险

    母乳喂养不仅能增强婴儿免疫力,还能降低母亲患乳腺癌的风险。

    建议:至少母乳喂养6个月,有条件可持续到1年以上。

    癌症从来都不是“突然降临”,而是“日积月累”的结果;同样,防癌也不是“一蹴而就”,而是“日复一日”的坚持。

    这份“防癌说明书”,照着做就能大幅降低患癌风险,护好自己和家人的健康。
