Universe Sandbox
La luna. Il nostro satellite, catalizzatore di sguardi romantici e sospiri lascivi per amori lontani. Il Sole, fonte di vita e di abbronzatura per stare alla moda. E tutto un turbinio di pianeti e stelle più o meno lontane, più o meno grandi e luminose. Corpi celesti affascinanti come i Quasar, le stelle di neutroni, i gamma ray burst, i buchi neri.
Sì lo ammetto, ho un deciso debole per l’atrofisica. Pur non capendone assolutamente nulla s’intende. Ma d’altronde per amare una cosa non è affatto necessario nè comprenderla nè esserne competenti. Sento che mi fischiano le orecchie riguardo un certo argomento cinematografico. Devo trovare un modo per cambiare rapidamente discorso.
Se c’è un altro debole che mi affligge, l’ultimo e poi basta nell’essere perfettissimo quale sono, è il delirio di onnipotenza. Già da piccolo questo mi valse molti rimproveri da parte di mia madre quando tentavo di separare le acque della minestra. Ma questa, come si suol dire è un’altra storia.
Dicevamo deliri di onnipotenza. Vi siete mai chiesti che cosa succederebbe al sistema solare se al posto del nostro piccolo sole ci fosse un buco nero dello stesso diametro ma di massa enormemente più grande? O se Giove avesse avuto massa a sufficienza per accendersi e creare con il Sole una stella doppia, tutt’altro che rara nell’universo? O ancora che cosa succederà alla nostra piccola Via Lattea quando si scontrerà tra qualche miliardaio di anni contro Andromeda (no, non il fratello finocchio di Phoenix). Infine: mai desiderato farvi una partita a bowling intergalattico?
Se la risposta ad almeno una di queste domande, o ad altri quesiti simili, è sì allora ho trovato quello che fa per noi. Si chiama Universe Sandbox.
Come il nome cerca di suggerire, Universe Sandbox non è altro che un software che simula il comportamento dei corpi celesti. In pratica si limita a mettere in atto calcoli basati su semplici formule gravitazionali che permettono di avere un comportamento più o meno realistico delle infuenze tra i vari corpi. Fornisce una serie di sistemi già pronti per essere visualizzati, come il sistema solare, il gruppo locale e via discorrendo.
La parte divertente del tutto non è ovviamente vedere delle palle che girano. Altrimenti basterebbe scendere in strada durante un ingorgo. Cosa che, per inciso, è divertente. Comunque sia Universe Sandbox prevede anche un notevole grado di interattività con i sistemi presenti nel simulatore. In qualsiasi momento è quindi possibile fermare il tempo e inserire un corpo celeste estraneo al sistema. Si può scegliere da una lunga lista di tipi predefiniti: un asteroide, una luna, un pianeta, una stella, eccetera. E se ne possono modificare le caratteristiche.
Le interazioni non finiscono ovviamente qui. Tutto quello che è già presente è modificabile. Può essere cancellato, oppure fatto più spettacolarmente esplodere, può diventare un buco nero o acquisire una nuvola di anelli come Saturno. Oppure si può colorare tutti i corpi celesti in funzione non del realismo ma della loro velocià di spostamento, creando effetti psichedelici da post Woodstock. Con molta buona volontà si può costruire un sistema solare alternativo, anche se devo ammettere che la parte più divertente è da sempre quella di distruggere, più che di creare. Non ci possiamo fare niente, noi poveri umani, ammiriamo se qualcuno sa costruire un grosso castello di sabbia in mare, ma segretamente desideriamo sempre di saltarci dentro e fare l’imitazione di Godzilla come nelle migliori strisce di Calvin & Hobbes.
E’ fin troppo ovvio che Universe Sandbox in realtà non è un vero e proprio “gioco”, anche se a conti fatti è il suo aspetto di intrattenimento ad essere prevalente, non essendo nemmeno un accurato e potente simulatore. Risulta quindi problematico riuscire a trovare un motivo per continuare a giocarci dopo un paio d’ore di utilizzo. E’ dotato di una longevità ridicola e rimarrà ben presto inutilizzato in qualche piega nascosta del vostro disco fisso.
Ah, quanto detto vale ovviamente solo per voi. Io non me ne riesco proprio a staccare, investito del mio ruolo di piccolo dio. E ora scusatemi, ma devo lanciare Marte nell’orbita della Terra.
Saluti,
Michele

Preserving Joe Davis Stadium to potentially host another Southern League team is out of the question. No owner would bring a franchise into Huntsville without a new stadium. Joe Davis Stadium lacks adequate skyboxes to serve as a major revenue stream for the club and its design – with concession stands out of sight of game action – is outdated. The stadium was constructed to 1985 codes, so even a massive makeover wouldn’t be feasible.

Or you use your kid锟絪 schedule as an excuse for a week of skipped workouts? Yes, it can be harder without a health-focused family, but with a few strategies under your belt you can stay on track!Make your goals known: So your family doesn锟絫 want to join your weight loss program, but do they know your goals? The first step to success is making your health goals clear to your family and asking for their support. If they understand your reasoning for skipping the Sunday morning donut trip, they will be more likely to encourage than tempt you.Respect your family锟絪 schedule: Yes, being single allows for more free time, but everyone can fit exercise into his or her schedule. If you have trouble working out when the day gets hectic, then go while the family sleeps. Get motivated, get up early, and get your workout done first thing. If you respect your family锟絪 schedule, they will respect your healthy me-time. Cook healthy: Nobody wants to eat a microwavable diet dish. Cook real food with whole ingredients for your family dinner that you and your family will enjoy. Also, make sneaky swaps whenever possible. Trade turkey meat for beef in hamburgers, swap Greek yogurt for sour cream on taco night and add veggies whenever possible.

The General Improvement Fund giveth and the Revenue Stablization Act taketh away is the rule of legislative funding by which the Red River Commission has been on life support for the past two years.Now, a bill by State Senator Jimmy Hickey, R-Texarkana, is in the pipeline to restore about $1 million to the Commission after its entire budget was gutted two years ago and shifted to higher education.Senate Bill 662 was filed by Hickey on March 2 and has since remained in the Joint Budget Committee without action.That might be the death knell for the bill, according to former senator Wayne Dowd, RRC representative from Texarkana. That General Improvement money is pretty iffy, Dowd said Monday. I am under the impression that there is about a million dollars. But, based on my experiencer, there is not any problem in passing it, the problem is getting it into the Revenue Stablization Act. SB662 provides $1 million in funds to be transferred to the Red River Waterways Project Trust Fund for costs associated with the project. The bill also provides special language for the special, local and temporary nature of the bill. Notwithstanding any other rules, regularions or provisions of law to the contrary the appropriations authorized in this Act shall not be restricted by requirements that may be applicable to other programs currently administered, the bill states. New rules and regulations may be adopted to carry out the intent of the General Assembly regarding the appropriations authorized in this Act. Dowd remained skeptical Monday. Our Red River Commission ad continued to meet mostly at our own expense, he said.Dowd said he had sought to contact State Representative Mary Hickerson, R-Texarkana, about funding for the Commission, and the RRC chair, Dan York, of Little River County, had contacted Hickey. I was getting pretty nervous, Dowd said. We were down to the 60th day of the session and a bill hadn’t been filed. Page 2 of 2 – In 2013, Hickey lead the effort to redirect the $10 million in funds which the RRC had developed over time, and divided it in the General Improvement Fund legislation between the Cossatot College of the University of Arkansas in DeQueen and the University of Arkansas Community College at Hope.UACCH, subsequently, used the funds to further develop its outreach campus in Texarkana. We’re not going to get the money to do that study, Dowd said at that time. We had a $5 million commitment toward that study and we were about $750,000 short; but, it just isn’t going to happen. The new potential funding Dowd said could help get the RRC back on track. It beats nothing, he quipped Monday.

Start with a deep breath and clear your mind. Commit to leaving worries and stress at the shower door, and instead focus on positive, energizing thoughts. Envision a carefree weekend activity, or recall the sights and sounds of a soothing tropical getaway. Channel your attention on creating positive energy.Set the mood with the right music and lighting. If you shower in the morning, give yourself a burst of energy with upbeat music and a brightly lit room. Conversely, if you鈥檙e winding down the day, mellow tunes and dimmed lights will help slow your pace.Moisturize your skin from head to toe with a hydrating body wash that leaves skin feeling soft and radiant. One option, Softsoap Fresh Glow Hydrating Shower Cream, is made with 100 percent real extracts sourced from milk, coconuts and almonds; the unique formula is proven to lock in long-lasting moisture.Though you may be tempted to let the steaming water soothe your skin and tired muscles, be wary of keeping the heat up too long. Excessive hot water can be harsh on your hair and skin, and strip skin of moisture. Opt instead for a lukewarm or slightly warmer temperature and finish with a cool blast to help seal pores and invigorate your spirit.Even if you鈥檙e short on time, commit to indulging in one pampering treatment each day, such as deep conditioning your hair or exfoliating tired skin. For smooth, healthy-looking skin that glows, consider Softsoap Fresh Glow Exfoliating Fruit Polish. Packed with exfoliating apricot seeds and made with 100 percent real extracts sourced from kiwi and orange, it鈥檚 a quick and effective way to moisturize and refresh your skin.

Fruit Loops 2 stars [url=http://michaelkorsoutlet.theahlis.com/]michael kors bags[/url] Originally, a Manhattan was always made with rye, but today, bourbon is the number one choice. Rye is drier and spicier than bourbon, but not nearly as complex or robust. Since by its nature bourbon is sweet, conventional wisdom dictates that a drier bourbon鈥攐ne with a higher rye content like or 鈥攃ombines best with sweet vermouth. However, that can depend on the vermouth you choose. I find , though wheated and sweet, has a much nicer body for Manhattan making, and when paired with Carpano Antica Formula vermouth, is just about as good as it gets. This vermouth (from the same people who produce Punt e Mes) has a unique bittersweet taste and a bottle costs about as much as a liter of Maker鈥檚 Mark, but is well worth it.
